Re: pg_dump fundenental question

Francisco,

appreciate the tips/hints.

My input (source) DB
is  1TB in size, using the options as stated in my original email (i.e. no
compression it would seem) the output file size is "only"
324GB. 
I presume all of the formatting/indices have been ommited. As I
said before, I can browse the backup file with less/heat/cat/tail etc.

Regards,

Henk

IIRC no options means you are requesting an SQL-script. Those
are not
compressed, just pipe them through your favorite compressor. ( In
a
later message you stated you were in Linux and had a 324Gb file, and
could head/tail it, have you done so? ).

OTOH, with those big backup I would
recommend using custom format (
-Fc ), it&#39;s much more flexible ( andyou
can have the sql script but
asking pg_restore to generate it if you need it,
but not the other way
round ).
