Create Database in PostGIS - postgis

At the moment, I have installed postGreSql 9.1 for windows with the extension of postGIS on it.
Now, I want to create a new Database in PostGIS.
Can someones guide me with an easy to follow and exact procedure on how to go about this, have gone through the documentation, but its too confusing.

Create database:
createdb mygeodatabase
Add PostGIS functions to it (PostGIS 2.0, PostgreSQL 9.2):
psql mygeodatabase
CREATE EXTENSION postgis;
With older PostGIS/PostgreSQL versions (your folders depend on OS):
psql -d mygeodatabase -f /usr/share/postgresql/9.1/contrib/postgis-1.5/postgis.sql
psql -d mygeodatabase -f /usr/share/postgresql/9.1/contrib/postgis-1.5/spatial_ref_sys.sql

postgres - convert .dat.gz file .sql file?

i received many .dat.gz files from a pg_dump at a postgres database.
i would like to convert it to a .sqli file to import it in a software like dbeaver.
Is there a way to do this? Unfortunately I can't find the answer by googling.
thanks
Take the below as suggestions and test before using in production.
At a guess is was some form of pg_dump -Fd ... per pg_dump.
If that is the case and all the files are there you can either do:
pg_restore -f dump.sql /dat_dir
which will create a plain version of the dump or:
pg_restore -d some_db -C /dat_dir
which will restore directly. In this case using -d to connect and then -C to create the database that was dumped.
For more information see pg_restore

postgreSQL error initdb: command not found

i was installing postgresql on ubuntu using linuxbrew:
brew install postgresql
it seems to work fine but after that because i was installing PostgreSQL for the first time i tried creating a database:
initdb /usr/local/var/postgres -E utf8
but it returned as:
initdb: command not found
i tried running the command with sudo but that doesn't helped
run locate initdb it should give you the list to chose. smth like:
MacBook-Air:~ vao$ locate initdb
/usr/local/Cellar/postgresql/9.5.3/bin/initdb
/usr/local/Cellar/postgresql/9.5.3/share/doc/postgresql/html/app-initdb.html
/usr/local/Cellar/postgresql/9.5.3/share/man/man1/initdb.1
/usr/local/Cellar/postgresql/9.6.1/bin/initdb
/usr/local/Cellar/postgresql/9.6.1/share/doc/postgresql/html/app-initdb.html
/usr/local/Cellar/postgresql/9.6.1/share/man/man1/initdb.1
/usr/local/bin/initdb
/usr/local/share/man/man1/initdb.1
So in my case I want to run
/usr/local/Cellar/postgresql/9.6.1/bin/initdb
If you don't have mlocate installed, either install it or use
sudo find / -name initdb
There's a good answer to a similar question on SuperUser.
In short:
Postgres groups databases into "clusters", each of which is a named collection of databases sharing a configuration and data location, and running on a single server instance with its own TCP port.
If you only want a single instance of Postgres, the installation includes a cluster named "main", so you don't need to run initdb to create one.
If you do need multiple clusters, then the Postgres packages for Debian and Ubuntu provide a different command pg_createcluster to be used instead of initdb, with the latter not included in PATH so as to discourage end users from using it directly.
And if you're just trying to create a database, not a database cluster, use the createdb command instead.
I had the same problem and found the answer here.
Ubuntu path is
/usr/lib/postgresql/9.6/bin/initdb
Edit: Sorry, Ahmed asked about linuxbrew, I'm talking about Ubuntu.
I Hope this answer helps somebody.
I had a similar issue caused by the brew install postgresql not properly linking postgres. The solve for me was to run:
brew link --overwrite postgresql
you can add the PATH to run from any location
sudo nano ~/.profile
inside nano go to the end and add the following
# set PATH so it includes user's private bin if it exists
if [ -d "/usr/lib/postgresql/14/bin/" ] ; then
PATH="/usr/lib/postgresql/14/bin/:$PATH"
fi
and configure the alternative
sudo update-alternatives --install /usr/bin/initdb initdb /usr/lib/postgresql/14/bin/initdb 1

How to import .bacpac into docker Sqlserver?

I installed Sqlserver on my Mac in a docker container, following the instructions from this article.
I run the container with Kitematic and managed to connect to the server using Navicat Essentials for SQl Server.
The server has four databases and I can create new ones, but, ideally, I would like to import an existing database as .bacpac.
The instructions from this answer have been of use to me in the past. Can I run something similar within the container? Or, more generally, is there a way to import a database in the container?
Hi all! We finally have a preview ready for sqlpackage that is built on dotnet core and is cross-platform! Below are the links to download from. They are evergreen links, i.e. each day a new build is uploaded. This way any checked in bug fix is available the next day. Included in the .zip file is the preview EULA.

Release notes:
The /p:CommandTimeout parameter is hardcoded to 120
Build and deployment contributors are not supported
a. Need to move to .NET Core 2.1 where System.ComponentModel.Composition.dll is supported
b. Need to handle case-sensitive paths
SQL CLR UDT types are not supported.
a. This includes SQL Server Types SqlGeography, SqlGeometry, & SqlHierarchyId
Older .dacpac and .bacpac files that use Json serialization are not supported
Referenced .dacpacs (e.g. master.dacpac) may not resolve due to issues with case-sensitive file systems
For lack of a better method, please provide any feedback you have here on this GitHub issue.
Thanks for giving it a try and letting us know how it goes!

EDIT: I've made you a Docker image for this
https://hub.docker.com/r/samuelmarks/mssql-server-fts-sqlpackage-linux/
Example of setting up a container, creating a database, copying a .bacpac file over, and importing it into aforementioned database:
docker run -d -e 'ACCEPT_EULA=Y' -e 'SA_PASSWORD=<YourStrong!Passw0rd>' -p 1433:1433 --name sqlfts0 samuelmarks/mssql-server-fts-sqlpackage-linux
docker exec -it sqlfts0 /opt/mssql-tools/bin/sqlcmd -S localhost -U SA -P '<YourStrong!Passw0rd>' -Q 'CREATE DATABASE MyDb0'
docker cp ~/Downloads/foo.bacpac sqlfts0:/opt/downloads/foo.bacpac
docker exec -it sqlfts0 dotnet /opt/sqlpackage/sqlpackage.dll /tsn:localhost /tu:SA /tp:'<YourStrong!Passw0rd>' /A:Import /tdn:MyDb0 /sf:foo.bacpac
It looks like Microsoft has implemented support of this on sqlpackage, with documentation!
You will have to add sqlpackage to your container.
You can download it here. (optionally, direct link to linux package here, hopefully doesn't change)
The following are instructions for running this from a windows machine -- obviously it's the bare minimum to get it working. Please change passwords, and probably put this in a docker-compose.yml for re-use.
I unzip the above package into a folder 'c:\sqlpackage' (my windows docker run doesn't allow relative paths), and then mount that into the container with the bacpac, like such:
docker run -d -e "ACCEPT_EULA=Y" -e "SA_PASSWORD=Asdf1234" -v c:\sqlpackage:/opt/sqlpackage -v c:\yourdb.bacpac:/tmp/yourdb.bacpac -p 1433:1433 --name mssql-server-example microsoft/mssql-server-linux:2017-latest
here is what a *nix user could run alternatively:
docker run -d -e 'ACCEPT_EULA=Y' -e 'SA_PASSWORD=Asdf1234' -v ./sqlpackage:/opt/sqlpackage -v ./yourdb.bacpac:/tmp/yourdb.bacpac -p 1433:1433 --name mssql-server-example microsoft/mssql-server-linux:2017-latest
and finally, attach to your container and run:
/opt/sqlpackage/sqlpackage /a:Import /tsn:. /tdn:targetdbname /tu:sa /tp:Asdf1234 /sf:/tmp/yourdb.bacpac
After this, you should be able to connect with SSMS to localhost, username and password as you provide them above, and see 'targetdbname'! These are mostly notes I wrote for myself but I'm sure others could use them too.
You can use free Azure Data Studio from Microsoft. Once you have it installed, install the extension "Admin Pack for SQL Server" from Microsoft. Then you can import bacpac files with ease.
This is not a supported feature with a LINUX implementation it seems.

Not allowed do anything in PostgreSQL

I've seen plenty of answers across the internet saying that to combat the
psql:FATAL: role <username> does not exist
one must use the createuser command, but about a dozen different attempts with that command have only yielded a similar error message.
I've installed PostgreSQL using Ubuntu 15.04's sudo apt-get install postgresql, but PostgreSQL permits to do absolutely nothing.
Do I need to install some dependencies or something?
Try doing these actions as the postgres user:
$ sudo -u postgres -i
The PostgreSQL installation makes a postgres user which runs the PostgreSQL service. It is essentially the superuser of your database. In most cases, you don't know the password for this user but any superuser of a system can log in to other accounts.

how to use the postgres database embedded with Mac Lion?

i can only find psql command, but can't find any other postgres commands or tools, can
anyone tell me how to create database and connect to it using the default postgres
shipped with mac lion?
only if it doesn't work ,i dont' want to install another postgres instance.
PostgreSQL will be started by Launchd, if configured so.
Look for /System/Library/LaunchDaemons/org.postgresql.postgres.plist, this is an XML file and you will need to modify some settings there, like listen_address.
Default location for the PGDATA files is /var/pgsql, also found in the plist file above.
Cluster is owned by the _postgres user, so to access the “tools”, you should execute them via the sudo -u _postgres … prefix, like: sudo -u _postgres pg_ctl -D /var/pgsql -w start
I highly recommend creating another role with superuser permissions, as _postgres is sharing password with the Administrator account of your Lion.
You can also use the Server Admin tools for Lion to control PostgreSQL and other services:
sudo serveradmin list
# look for postgres in the output
sudo serveradmin fullstatus postgres
sudo serveradmin stop postgres
sudo serveradmin start postgres
Check the version of your PostgreSQL cluster, using: sudo -u _postgres psql -tc "select version()" and refer to the official manuals on how to create the database and setup initial access. Manual for the latest PostgreSQL version can be found here.
If you do not have the software installed, I strongly recommend the Enterprise DB package. It makes installing pretty darn easy.
