Hi,
Citing Ulrich Wisser <[EMAIL PROTECTED]>:
I would like to stop the postmaster every night and run
vacuum pg_dump reindex
in the stand alone backend.
Vacuum and reindex seem to be quite easy, as I can setup a small script with both commands. But what about pg_dump. That seems "somewhat" more complex.
What exactly is your problem about putting pg_dump in a (shell)script as well?
psql will not work without postmaster running. But if I let postmaster run some other tools will connect to it and I can't get exclusive locks on all tables for "vacuum full" and "reindex". With vacuum and reindex
I can do
#!/bin/bash postgres -d /var/lib/pgsql/data -U xxx -O -P mydb < SQL REINDEX DATABASE mydb REINDEX TABLE t1 FORCE REINDEX TABLE t2 ... REINDEX TABLE tn VACUUM FULL VERBOSE ANALYZE <<SQL
which will speed up my database on a daily basis at least by factor 5.
For security reasons I would also like to take a backup and I guess it will be much faster in the stand alone backend.
