Hello there,
One of our PostgreSQL 9.4.1 databases has been backed up as *.gz
file with the compression 9 "pg_dump -Z 9". What is the right format
of restore this file when needed? Can I run the restore from a
compressed file or I need to unzip the file first, then run
pg_restore? Thanks
It depends on whether you dumped using the custom format -Fc or
plain(no -F or -Fp). If the custom format then you run pg_restore
against it. If the plain format then you will to unzip first then feed
the file to psql.
What about this?
gunzip -c | foo.sql.gz | psql
gunzip -c | test_plain.gz | psql -d test_gz -U postgres
bash: test_plain.gz: command not found
gzip: compressed data not read from a terminal. Use -f to force
decompression.
For help, type: gzip -h
Null display is "NULL".
I think what you want is:
gunzip -c test_plain.gz | psql -d test_gz -U postgres
Null display is "NULL".

In any case that will only work if the *.gz file is a compressed plain
text format. My suspicion is it is, still I had to allow the possibility
that it is a custom format file that someone hung a gz extension on.
