The version of Postgres is 7.4.
When I said the process had terminated abnormally - what I meant was a UNIX
process (C program) had opened a database connection, run some updates
without a COMMIT and then exited without closing the connection to the
database or committing the transactions.
From what I see below, could I assume that the best method is to kill the
offending process in UNIX, and then postmaster should recognize there was a
problem and restart the database. Correct?
Thanks,
Kevin
