Working with postgresql 11

Good day. Does PBS work with postgresql 11? Or only with postgresql 9. On my server i already have postgresql 11 with databases and when im trying to install pbs, conflict arises between postgresql 11 and 9

Commercial PBS Pro is only compatible (ships) with Postgres 9 at this point. It has probably been done with OpenPBS since the spec file just says:

Requires: postgresql-server >= 9.1
Requires: postgresql-contrib >= 9.1

If you want to run both instances at the same time then they will need to be run on different ports otherwise they will conflict. You need to check the postgresql.conf config file. The default is probably 5432, change this for one of the DB’s.

Then make sure that the data directory, log file are unique for each instance.
