I think this is a bug in Ubuntu's version of getopt_long(); it does not
happen that way for me on any of the platforms I use. I get either
psql: FATAL: role "-cSELECT tablename FROM PG_TABLES limit 1;" does not exist
on platforms where getopt_long does not think it has a charter to try to
rearrange command line arguments, or
$ psql postgres -c"SELECT tablename FROM PG_TABLES limit 1;"
tablename
--------------
pg_statistic
(1 row)
on platforms where getopt_long does move the database name after the
switch+argument. What you've evidently got is a getopt_long that tries
to rearrange the command-line arguments but produces the equivalent of
psql "-cSELECT" "postgres" "tablename" "FROM" "PG_TABLES" "limit" "1;"
which is flat out wrong.
Recommendation is to use the documented command line order, which is
psql [OPTION]... [DBNAME [USERNAME]]
rather than assuming getopt_long will fix it for you.
You can try filing a bug against Ubuntu's glibc, but I dunno whether
you'll get any satisfaction there. I think we've heard of this before
and the misbehavior is of long standing.
