pgsql: Use placeholders and not GUC names in error message (autovacuum)

Use placeholders and not GUC names in error message (autovacuum)

A placeholder %s is now used instead of the GUC names in the error
string of this routine. This is going to be useful for a follow-up
patch, where we will be able to reuse the same string, hence reducing
the translation work.

Based on a suggestion by me.
