Fix quasseluser table setup on PostgreSQL and sort sql.qrc

It seems that at some point the DEFAULT option for a varchar()
column has become sensitive to whether or not single or double quotation
marks are used. In particular when ""s were used, core setup failed
with the message 'ERROR:  column "Database" does not exist'. Changing
to single quotation marks (''s) resolved the issue.

Also include @digitalcircuit's sorted version of sql.qrc.

Fix the upgrade script too.
