PostgresV2 Patch

Hi All,
Hi Yanni,

I committed a patch to PostgresV2:

Name: PostgresV2-SvenVanCaekenberghe.26
Author: SvenVanCaekenberghe
Time: 8 November 2011, 9:47:18 am
UUID: 8d3c478b-6e4b-43ec-bcd8-74c366222350
Ancestors: PostgresV2-YanniChiu.25

fixed timestamp with timezone parsing (old code assumed the timezone to be +HH:MM but this is no longer the case);
introduced PGConnection class>>#nextDateAndTimeFrom: that works with or without timezone and is more efficient;
PGConnection class>>#timestampConverter and #timestampWithTimezoneConverter now use #nextDateAndTimeFrom:
recategorized #nextBooleanFrom: #nextStringFrom: and readIntegerFrom: as private

Regards,

Sven
