[GENERAL] PostgreSQL 32 bit DB on 64 bit machine
Can a 32 bit PostgreSQL v. 9.0 db be copied from a 32 bit machine and overwrite the db on a 64 bit PostgreSQL machine? I'm trying to get a good initial starting point before performing hot standy write ahead logging (WAL) replication between a 32 bit and 64 bit machine. When I copy the 32 bit db to the 64 bit db, the PostgreSQL logs are saying the pg_control file has a checksum mis-match. When I backup and restore the 64 bit pg_control then the log files report a sys id mismatch.

For instance, from PG Admin III, right click on the database cylinder and choose the plain text options. You'll be left with a command something like this: pg_dump --host localhost --port 5433 --username postgres --format plain --create --clean --inserts --column-inserts --verbose --file "q:\donzbrane.sql" "Chess" (Here, I am sending the output of a database called 'Chess' to a SQL file called donzbrane.sql). By examining the options and command line choices for pg_dump from the manuals, you can also create exactly what you want. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

In that case, a 32-bit data directory may be used. > I think he can get what he wants by doing a SQL dump instead of an ordinary > dump. I tend to agree. Running a 32-bit DB on the 64-bit host won't tell them anything much for this case. -- Craig Ringer Tech-related writing: http://soapyfrogs.blogspot.com/ -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
