-## Procedural Languages {#module-services-postgres-pls}
-
-PostgreSQL ships the additional procedural languages PL/Perl, PL/Python and PL/Tcl as extensions.
-They are packaged as plugins and can be made available in the same way as external extensions:
-```nix
-{
-  services.postgresql.extensions = ps: with ps; [
-    plperl
-    plpython3
-    pltcl
-  ];
-}
-```
-
-Each procedural language plugin provides a `.withPackages` helper to make language specific packages available at run-time.
-
-For example, to make `python3Packages.base58` available:
-```nix
-{
-  services.postgresql.extensions = pgps: with pgps; [
-    (plpython3.withPackages (pyps: with pyps; [ base58 ]))
-  ];
-}
-```
-
-This currently works for:
-- `plperl` by re-using `perl.withPackages`
-- `plpython3` by re-using `python3.withPackages`
-- `plr` by exposing `rPackages`
-- `pltcl` by exposing `tclPackages`
