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
