You didn't specify the Postgres version - that matters, because older
pg_dump versions (before PG 16) do not support compression. Since PG 16
you can use either -Fc or -Fd (instead of the tar format), and it'll
compress the output using gzip.
Oh, it goes back further then that:
https://www.postgresql.org/docs/7.1/app-pgdump.html
"-F format, --format=format
Format can be one of the following:
p
output a plain text SQL script file (default)
t
output a tar archive suitable for input into pg_restore. Using
this archive format allows reordering and/or exclusion of schema
elements at the time the database is restored. It is also possible to
limit which data is reloaded at restore time.
c
output a custom archive suitable for input into pg_restore.
This is the most flexible format in that it allows reordering of data
load as well as schema elements. This format is also compressed by default.
"
Alternatively, you can use --compress=method:level (the supported
methods depend on how the packages were built, no idea what platform
you're on etc.). See
https://www.postgresql.org/docs/current/app-pgdump.html
If you're on older version, you should be able to write the dump to
standard output, and compress that way. Something like
pg_dump -Fc | gzip -c > compressed.dump.gz
However, be aware that pg_dump is more an export tool than a backup
suitable for large databases / quick recovery. It won't allow doing PITR
and similar stuff.
