Hello -
I'm using PG 8.2.4.
I am executing a function which includes the code fragment shown below. It
goes through the loop and then fails with the error message
ERROR: relation with OID 591161 does not exist
I'm using the serial data type as a way to record the order of the records
based on a specific sort. I thought that by dropping the table and
recreating it that I would start off with a fresh counter each time. I
suspect that I do not understand something about how the SQL is compiled and
stored, and that the OID is related to this.
I have included the output below the code.
Any guidance would be appreciated.
Thank you.
