Tom Lane 870df2b3b7 Fix omission of -X (--no-psqlrc) in some psql invocations.
As of commit d5563d7df, psql -c no longer implies -X, but not all of
our regression testing scripts had gotten that memo.

To ensure consistency of results across different developers, make
sure that *all* invocations of psql in all scripts in our tree
use -X, even where this is not what previously happened.
