Add option --remove_pg_catalog_from_functions

[borisz]

The new option removes the pg_catalog schema before function calls.
These may occur when PG replaces the desired function with an
adequate other function.

# output without the new option

❯ pgpp -m 100 -S "select substring('123',2,3), btrim('xxx'), trim('xxx'), POSITION('hour' in trim(substring('xyz hour ',1,6)))"
SELECT pg_catalog.substring('123', 2, 3)
     , btrim('xxx')
     , pg_catalog.btrim('xxx')
     , pg_catalog.position(pg_catalog.btrim(pg_catalog.substring('xyz hour ', 1, 6)), 'hour')

# new output with -F

❯ pgpp -F -m 100 -S "select substring('123',2,3), btrim('xxx'), trim('xxx'), POSITION('hour' in trim(substring('xyz hour ',1,6)))"
SELECT substring('123', 2, 3)
     , btrim('xxx')
     , btrim('xxx')
     , pg_catalog.position(btrim(substring('xyz hour ', 1, 6)), 'hour')
