Thread: pg_dump

Does anybody know:

1) Is the tar/custom format of pg_dump is portable accross different  platforms?

2) if I want to dump out all of database cluster contents including  large objects, is following procedure correct?
  (dump procedure)  pg_dumpall -g  pg_dump -F c .... for each database   :   :
  (restore procedure)  initdb  psql template1 < dumpout_of_pg_dumpall  pg_restore ... for each database

It's supposed to be; if it's not, it's a bug.

Looks OK to me. You need a '-b' on the pg_dump (for BLOBS), and each dump
command will need to go to a separate file - it won't currently work if
multiple dumps are being sent to stdout.

This latter could be fixed (at least for 'c' format) by modifying pg_dump
to use open/read/write/lseek instead of fopen/fread/fwrite/fseek etc.
