Not a direct answer, but how's about using CSV files instead of dumps?
You can instruct SQL Loader about the format of incoming dates via the
control file (ctl.)
BTW, I just did a migration in the other direction using CSV files. I
must say I never cease to be impressed by the robustness of PostgreSQL.
Oracle exported dates like this: "9/14/2004 6:40:21 PM". PG took 'em
right in with no special instructions, and produced the correct
timestamp. Hats off to the PG developers! Thanks for all your work.
