Good afternoon,
Probably an easy question but why are the file sizes differ so much between
these two tools?
For example:
A backup using pg_dump of our largest DB creates a file 384MB in size
Using the following SQL code utilizing dbsize I get the following:
FIX1=# SELECT D1.pg_size_pretty AS "FIX1_DB_SIZE"
FIX1-# FROM (SELECT pg_size_pretty(database_size('FIX1'))) D1;
FIX1_DB_SIZE
--------------
3832 MB
(1 row)
Is it safe to assume that pg_dump does a compression of the data?
Thanks
Tim
