Currently, test/regress/sql/psql.sql doesn't AFAICS write anything
outside of stdout, but \g, \o, \copy need to write to external
files to be tested properly.

Looking at nearby tests, I see that commit d1029bb5a26 brings
interesting additions in test/regress/sql/misc.sql that could be used
as a model to handle output files. psql.sql could write
into PG_ABS_BUILDDIR, then read the files back with \copy I guess,
then output that again to stdout for comparison. I'll see if I can get
that to work.
