I have a DB with is updated using MS Access. Primary keys are Int4 with default random values ("NuméroAuto" +
"Aléatoire"in Access).
The DB is migrated as-is in Postgres, with tbl_prod.cle_prod field containing values from -2057496808 to 2139583719.
When I SELECT in the table, using the INT4 cle_prod value, PG doesn't find the tuple. When I SELECT using the
VARCHAR(10)ref_prod value, PG finds the tuple, and show the right value for the cle_prod filed : the same as the one I
SELECTedfor...
This sounds like the long negative integer values given in PSQL is not converted correctly while executing.
Using a long positive integer value, all works like a charm...
Below is the queries type sto sho what append.
I'm using Postgres 6.5.2 from the RPMs.
