Use separate SQLSTATE codes for file not found/file exists, rather than

Refactor code so that to_date() does not call to_timestamp() and then

problems with timezone dependency of to_date's result, and should be

Improve dynahash.c's API so that caller can specify the comparison function
as well as the hash function (formerly the comparison function was hardwired
as memcmp()). This makes it possible to eliminate the special-purpose
hashtable management code in execGrouping.c in favor of using dynahash to
manage tuple hashtables; which is a win because dynahash knows how to expand
a hashtable when the original size estimate was too small, whereas the
special-purpose code was too stupid to do that. (See recent gripe from
Stephan Szabo about poor performance when hash table size estimate is way
off.) Free side benefit: when using string_hash, the default comparison
function is now strncmp() instead of memcmp(). This should eliminate some
part of the overhead associated with larger NAMEDATALEN values.

libpq failed to cope with COPY FROM STDIN if the command was issued

a wart on the protocol, but little alternative. Also, libpq must send
