Обсуждение: reviving "custom" dump
Short version: Does a current version of postgres tolerate ascii dumps from older versions?
I've been charged with reviving an old project. I have a dump dated July of 2021 which file tells me is a "PostgreSQL custom database dump V1.13-0". If our compute centre won't roll me a V12(?) postgres server, I'll need to use an "office" machine to bring this dataset back to life. If I pull that off can I make an ascii dump and import that into our main db server (V14) or will I have to also install V14 in the office and dump/restore with that?

You should read the description and notes sections for how this command works and its capabilities and potential limitations.

Off by one error here perhaps: I have a custom dump in hand, it's restoring that is the problem. But pretty sure the take home from pg_restore is "Use the newer version both ways".
