Hi all.
I have a database with very large tables - about 2+ GB per table.

When I'm using pg_dump tool, it get all memory available, then linux
crash (or kernel kills the most of processes including pg_dump)

For this reason I made small php script which dump data using 'fetch
next in cursor' (PHP is lame for this but is perfect for me).
I tried to patch pg_dump, but I cant understand most of the code (never
works with pg blobs from C).

I'm attaching the files I use in order to share them with all you.

Nikolay.

P.s.
Shell scripts are for calling the php scripts.
dump1.sh - create list with shell commands needs to be executed in order
to get backup.
dump.sh - backup single table

P.s.

Is there any interest for discussing very large pg database programming
and administration or is such list exist?
