Check decoding of integer in x - y syntax (already done for most ints).

 hardcoded values.

Check valid numeric input more carefully for delta times.
Implement day of year as possible input to datetime_part().

Remove unused variable addrLen.

Adjust a few other tests to be more complete.

Cross-reference libpq(3).

Add pg_description table for info on tables, columns, operators, types, and aggregates.  Modify psql with new \dd operator to access description

Rename PG_DATESTYLE to PGDATESTYLE environment variable.
Move environment variable code to a different place so it now works!
Note that regression tests can now run with "setenv PGTZ PST8PDT"
 at the frontend rather than requiring the backend to have TZ set.

Try to save pre-existing TZ environment variable if possible.
