Two questions.
I could, of course, create a data-only dump (in fact I've already done it). However, when restoring, I cannot use pg_restore since it's in plain format, don't you? pg_restore only works with tar or compressed formats, I think. I could restore data-only dump with psql, but then I've to disable triggers and psql does not have an option in order to disable them.
Second one. You say I could restore a compressed dumpfile into a plaintext file. Is this possible? How? And after cleaning this plaintext file, how do I restore it again into database without using psql since pg_restore only accept tar or compressed file formats?
Thank you, Josh.

Third one, and we haven't been able to fix it, is we cannot restore data dump via psql due to psql does not have an option to disable triggers. So, when restoring data, it fails. So... is there any way to disable in a psql session all triggers same way like with pg_restore --disable-triggers? Or can we convert plain text dump to be processed by pg_restore? Perhaps a table by table trigger disabling script?
How about: 1. restore your schema, with triggers, using a pg_dump --schema-only ... ; pg_restore ... 2. Create a psql-loadable data-only dump using pg_dump --data-only --disable-triggers --format=p ... 3. clean the data-only dump and restore
Or, you could do a full pg_dump -Fc ... of your database, then use pg_restore to restore the compressed dumpfile into a plaintext file (i.e. pg_restore [options] filename). Then run your cleanup on the plaintext file, and reload.
