From 7355535ee18efc472f5a598b8474e8d05765d6f1 Mon Sep 17 00:00:00 2001 From: Jacob Anawalt Date: Mon, 11 Oct 2010 18:53:00 -0600 Subject: Enable pg_dump format option. The format option of pg_dump enables tar and custom archive file formats in addition to the default plain-text file containing SQL commands. When either the tar or custom format are selected the behaviour of database=all is changed to no longer dump a single file via pg_dumpall. Instead pg_dumpall is called once to export the "global" data (roles & tablespaces) and then pg_dump is called once for each non-template table in the database. To support the GZIP and GZIP_OPTS variables in backupninja and to give the default --rsyncable gzip compression flag a chance at working on a PostgreSQL backup, the custom output is forced to not use compression. Instead compression is done via a pipe to gzip. Hopefully this benefits rsync and rdiff-backup style backups for reduced backup and storage costs that outweigh the restoration ones. --- examples/example.pgsql | 13 +++++++++++++ 1 file changed, 13 insertions(+) (limited to 'examples') diff --git a/examples/example.pgsql b/examples/example.pgsql index 42f045e..5a4e02f 100644 --- a/examples/example.pgsql +++ b/examples/example.pgsql @@ -17,6 +17,19 @@ # compress = < yes | no > (default = yes) # if yes, compress the pg_dump/pg_dumpall output. +# format = < plain | tar | custom > (default = plain) +# plain - Output a plain-text SQL script file with the extension .sql. +# When dumping all databases, a single file is created via pg_dumpall. +# tar - Output a tar archive suitable for input into pg_restore.
