Postgresql 12 doesn´t find PostGIS extension on CentOS 8 - postgresql

I´m trying to get PostGIS working, but it seems that Postgresql doesn´t find the extension. My server is running on CentOS 8, the Postgresql is version 12. I installed Postgresql 12 first via dnf module enable postgresql:12 etc..
Afterwards I installed PostGIS and followed the description on the PostGIS website (https://people.planetpostgresql.org/devrim/index.php?/archives/102-Installing-PostGIS-3.0-and-PostgreSQL-12-on-CentOS-8.html). But when I try to run CREATE EXTENSION postgis; I get the error ERROR: could not access file "$libdir/postgis-3": No such file or directory SQL state: 58P01 I figured out that the needed files reside in a subdirectory "bitcode". Therefore I tried to symlink the content in the $libdir directory above - but didn´t help. Even copying them in the directory didn´t - same error. What am I missing?
Thank you and best regards,
Goetz

You have a mix of packages installed: Some from the CentOS distribution, some from the PostgreSQL site. That will lead to trouble.
Uninstall the PostgreSQL packages that do not have PGDG in them and make sure to disable them as shown in the link you show. Then install the PGDG packages for PostGIS

Postgres 12 Extensions Not Installed on RHEL 7

Looking to install the pgstattuple extension on my Postgres 12 DB on RHEL 7 to see index fragmentation. Currently I only have one extension installed and that's the plpgsql extension.
Executing 'CREATE EXTENSION pgstattuple' results in the following error:
SQL Error [58P01]: ERROR: could not open extension control file "/usr/pgsql-12/share/extension/pgstattuple.control": No such file or directory
And I verified that the pgstattuple.control is not located in the /usr/pgsql-12/share/extension folder.
Searching around the net, seemed to indicate that the postgresql-contrib needed to be installed to get the pgstattuple extension. So I did the following command:
$ sudo yum install postgresql-contrib
Unfortunately the yum install postgresql-contrib resulted in the pgstattuple and other extensions being installed into the /usr/pgsql-9.6/share/extension
folder, and not in the /usr/pgsql-12/share/extension folder where I want them.
For giggles, I tried copying all the pgstattuple* files in /usr/pgsql-9.6/share/extension to /usr/pgsql-12/share/extension folder, and then tried calling CREATE extension pgstattuple, but that didn't work with another error.
Questions are:
Should I expect sudo yum install postgresql-contrib to actually install the pgstattuple extension for Postgres 12?? Or is there some other package name for Postgres 12?
Could this be some problem with my Red Hat Repository configuration?
In general what's the command to install the pgstattuple extension for Postgres 12 so that the pgstattuple files will end up in /usr/pgsql-12/share/extension folder??
Really appreciate any suggestions you have.
Thank you.

Postgres extension missing after upgrade

I have just upgraded my development postgres cluster from postgreSQL 9.6 to 11. Everything went fine except that I got an error around the pgtap extension that I use for unit testing.
Now when I try to restore a database I'm getting an error
"ERROR: could not open extension control file "/usr/share/postgresql/11/extension/pgtap.control"
When I look in the file system I can see all the pgtap files are still in /usr/share/postgresql/9.6/extension.
I tried uninstalling pgtap running sudo apt-get purge --auto-remove pgtap and then re-installing but this hasn't worked, all the files are still in the 9.6 directory.
pgTAP is a third-party extension, you won't find anything about it in the PostgreSQL manual.
You will have to install it separately in your v11 PostgreSQL installation. See the installation instructions for pgTAP.

How to install Postgis to a Keg installation of Postgres#9.6 using Homebrew?

I have installed Postgresql#9.6 and Postgis via Homebrew. However, installing Postgis via Homebrew installs the latest version of Postgresql at 10 as dependency and pinning Postgresql at 9.6.5 blocks the install of Postgis via Homebrew.
Performing 'CREATE EXTENSION postgis;' returns:
ERROR: could not open extension control file "/usr/local/Cellar/postgresql#9.6/9.6.5/share/postgresql#9.6/extension/postgis.control": No such file or directory
I've also tried uninstalling the Postgresql (at 10) and editing the Postgis formula to depend on Postgres#9.6 instead of Postgresql.
This is similar to How to install Postgis to a Keg installation of Postgres#9.5 using Homebrew? but with a later keg formula
I managed to do it after many combinations.
In a nutshell, solution is to install the old version of the original package postgres, switch to it, and install the old version of postgis.
Install postgres
1/ Install the current version of postgres (10.1 as speaking)
brew install postgres
2/ Install the old version of postgres using its old formula. Proper link can be found using github or git log on the Tap repo (/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/).
brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/d014fa223f77bee4b4097c5e80faa0954e28182f/Formula/postgresql.rb
This will install the version 9.6.5 (last one before 10.x series).
3/ Switch to it so links are defaulted to postgres 9.6
brew switch postgres 9.6.5
Install postgis
4/ Install old version of postgis (2.3). This is using the same sha version of the Formula so everything is linked correctly (using the current postgis will expect postgresql 10, so it will end up to a version mismatch when initializing extension).
brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/d014fa223f77bee4b4097c5e80faa0954e28182f/Formula/postgis.rb
Use them
5/ If required initialise the DB
initdb /usr/local/var/postgres
6/ Create and use your DB
createdb mydb
psql mydb
mydb=# CREATE EXTENSION postgis;
Installing PEX, a package manager for Postgresql allowed me to install Postgis for the keg version of Postgresql#9.6 and use CREATE EXTENSION postgis;
This isn't a Homebrew solution but after a lot of searching, it finally allowed me to use Postgis.
HelloI ran into this same problem of multiple implementation of pgsql versions including legacy ones. So after a bit of research I would like to share my solution.
Problem:
I am working on a macbook pro 2013 with 10.11 el capitan. I am GIS developer and extensive user of homebrew. I didn't pin the postgresql package for compatibility reasons. Thus, the package got updated to postgresql version 10.5 along other packages. This caused me to be unable to use postgresql version 9.4. The cleverest solution would have been to use a brew switch postgresql 9.4.19. Except that when compiling postgis 2.5.0 from osgeo/osgeo4mac it defautls (looks for) the postgresql binary folder to install the symlinked (or not) extensions. Here again another compatibility problem. One could tinker a bit with homebrew files and transfer files manually. That's ill advice...the package manager (homebrew) needs to stay a coherent ecosystem to provide for a stable workspace.
Proposed Solution:
Go here BigSQL and download the dmg of your chosen version
install the software where you want in your filesystem
within the installation folder you'll find a directory named pg9x ; x being the version number (e.g pg95 for postgresql 9.5 and so on...
in this folder you'll find a file named pg9x.env
source this file to your .profile with source /your/path/pg9x/pg9x.env line
in the main installation folder, for instance /your/path/pg9x/, you'll finde a python script called pgc, alias it to your .profile with alias pgc="your/path/pgc"
save your .profile and refresh your environment variable with source .profile on the command prompt
still within the command prompt, type pgc list, you'll get a list of installed packages. You'll see the version of postgesql you've downloaded
to install another version of postgresql, say 9.6, type pgc install pg96
to install postgis for pg95 type pgc install postgis22-pg95
to install postgis for pg96 type pgc install postgis23-pg96
now, after installation you'll need to initialize the downloaded component with pgc init pg96 or pgc init postgis23-pg96 etc...
to check if your daemon is running correctly type pgc status
to start a version daemon of your choice type for example pgc start pg95
to stop a version daemon of your choice type pgc stop pg95
the installation also comes with an LTS release of pgadmin3 that works fine with all versions (not the case of brew version of pgadmin3), this is very convenient
type pgc help for more options
Let the elephant dance^^
Hope this helps.
Spicy.
I faced a similar issue and what worked for me was to follow the instructions at https://github.com/CloverHealth/homebrew-tap, which seem similar in spirit to #Antwan's solution but with a few more clean up steps, also it gets slightly later versions: postgresql 9.6.10 and postgis 2.5.
My steps differed slightly from those at CloverHealth: My brew version no longer supports brew switch postgresql 9.6.10 and I tried first brew link postgresql#9.6.10 and then brew link postgresql#9.6 but both gave
Error: no such keg
Trying brew search postgresql showed a little green checkmark next to the cloverhealth Formulae, so I tried brew link cloverhealth/tap/postgresql and got
Warning: Already linked: /usr/local/Cellar/postgresql/9.6.10
So, ok it was already linked. Other than that my steps were the same as described at the CloverHealth page, and now I'm up and running again.

How to install Postgis to a Keg installation of Postgres#9.5 using Homebrew?

I have installed Postgresql#9.5 to my OSX El Capitan Machine using Homebrew 1.2. Unfortunately, upon installing Postgis, and performing CREATE EXTENSION postgis;
It returns,
ERROR: could not open extension control file "/usr/local/Cellar/postgresql#9.5/9.5.6/share/postgresql#9.5/extension/postgis.control": No such file or directory
I tried, uninstalling all postgresql and install only the 9.5 version, and then installing postgis but to no avail.
I think I got a similar question but this one is only for Ubuntu.

This discussion also instruct to install postgresql using # notation but didn't tell that it will create a non-comformant directory name

Postgis - Failed to install it on linux mint mate 17

I install postgis via sudo apt-get install postgis postgresql-9.3-postgis-2.1
Then execute CREATE EXTENSION postgis; but got following error tip:
ERROR: could not load library "/usr/lib/postgresql/9.3/lib/postgis-2.1.so":
/usr/lib/postgresql/9.3/lib/postgis-2.1.so: undefined symbol: HeapTupleHeaderGetDatum
I am using postgresql 9.3.4, and postgis-2.1.
I did google for over an hour, but didn't found a solution that really solve my issue.
Any help?
I spend another hour, and finally tried to install it from source code, and succeed like a charm, no single issue occur!
Here is the link provide detail steps to install postgis from source code:
http://trac.osgeo.org/postgis/wiki/UsersWikiPostGIS21Ubuntu1404src
It also works for my Linux mint mate 17, which is base on ubuntu 14.04.
The first two hits seem to say basically the same thing to me:
http://www.postgresql.org/message-id/A9A6BC42-D2E2-471B-BFB0-F6A72EF42911#conundrum.com
https://github.com/pgRouting/pgrouting/issues/271
It sounds to me like your version of postgis was built against a version of postgresql later than 9.3.4 which included a bugfix that included "HeapTupleHeaderGetDatum". So - upgrade your postgresql (you do have something more recent than .4?) and/or make sure you get postgis from the same repo as your postgresql packages.
See if that helps.
