Someone can help me .... I have a compatibility problem between Postgres 7.1 - Postgres 7.3... Guess !!! It's --- timestamptz --- When I create a field with timestamp type... the new postgresql replace that by timestamptz.... I use phpPgAdmin, I don't know where is from the problem... Simple example, If I execute that : CREATE TABLE "statistic" ( "Id" int4 NOT NULL, "DATE" timestamp); I shall have that on the database: CREATE TABLE "statistic" ( "Id" int4 NOT NULL, "DATE" timestamptz); Grrrrrr, =) Helpsssssss, Areski
