pgsql: Fix postgresql.conf lexer to accept doubled single quotes in - Mailing list pgsql-committers

Log Message:
-----------
Fix postgresql.conf lexer to accept doubled single quotes in literal
strings.  This is consistent with SQL conventions, and since Bruce
already changed initdb in a way that assumed it worked like this, seems
we'd better make it work like this.
