Re: CLI for Schema Diff

Hey all,

In case anyone is interested, I've managed to enable a CLI mode for the
Schema Diff on this repo:

https://github.com/steve-chavez/pgadmin4/blob/cli/web/cli.py

It basically works by using a Flask test client that interacts with the
Schema Diff endpoints.
It's a single isolated file, I haven't patched any of the existing modules.

For a quickstart, there's also a docker image that can be used like:

docker run supabase/pgadmin-schema-diff \
'postgres://postgres(at)host/diff_source' \
'postgres://postgres(at)host/diff_target' \
> diff.sql
## the stderr output shows the same messages as the Schema Diff GUI:

Starting schema diff...
Comparision started......0%
Comparing FTS Dictionaries ...35%
Comparing Functions ...50%
Comparing Trigger Functions ...60%
Comparing Sequences ...70%
Comparing Tables ...80%
Comparing Views ...90%
Done.
