Обсуждение: Deadlock Detection

How do I find out in Embedded SQL that a transaction has been aborted
due to a deadlock?

The closes error message in sqlca seems to be:

  -401 (ECPG_TRANS): Error in transaction processing line %d.
   PostgreSQL signaled that we cannot start, commit, or rollback the
   transaction.

but it does not seem to be informative enough.

I don't think anyone on the NOVICE list has much familiarity with Embedded
PGSQL.  Try the HACKERS list instead.

FWIW, in 7.4 we will have SQLSTATE standards-compliant error codes which will
make analyzing such errors easier.

Hi,
I am using postgresl 7.2.3. Yesterday i have dumped a database using pg_dump
everthing was fine, but the dump was in the wrong order. There were indexes
and views createded before the corresponding table was created.
Its not a big deal but editing 250MB asciifiles isnt actually fun :)

i used "pg_dump dbname > dbname.sql" to dump and "pgsql dbname < dbname.sql"
to restore the database.

Did i missed something?
Are files dumped with pg_dump supposed to be restored with pg_restore or is
it a bug?

Regards
Thilo Hille

There are some bugs along that line, particularly in older releases.
If you're using one of the archive output formats then pg_restore can
be used to alter the restore order into something that will work.
