auto fill the missing numbers

i have recently converted an ms access program using the standard jet
backend over to postgres using an ODBC driver, i have managed to sort most
bugs out except this one

ms access already had some 57000 transaction loaded into the old database,
when i linked to postgres using the ODBC driver, all these transaction came
over, as excepted, but when i create a new record now, the database is
filling in all the missing numbers prior to 57000, which jumbles up my
record table. How can i get the postgres database to start off from 57001

any help would be a help

I am guessing here but likely you have an autoincrementing number that
the sequence was set to 1. I suggest you look into setval() in the docs.

I assume that by transaction you mean record I assume that you are using =
serial or big serial as
the autonumber for your new postgresql tables.

1) you need to determine the table_sequence name that was created for you=
table.
2) change the table_sequence value to one greater than the values already=
stored in the table from
access.

The function you need it setval()
http://www.postgresql.org/docs/8.2/interactive/functions-seq uence.html

you can use setval() useing the psql client utility to postgresql.
