I find PostgreSQL permission management quite convoluted. In MySQL it is simple to query for what grants a user has, but in PostgresSQL you need to write 100 lines of SQL to do the same... and you can't run \du and other commands without psql. Why couldn't they just come up with `SHOW` shortcuts that work in any SQL client?
You can likely get the SQL for a meta command, and you could run the SQL from your preferred client if you don’t use psql. Here is one example: https://dba.stackexchange.com/a/131031
I also highly recommend investing in psql skills though if you are a Postgres user.
Yes, that's the "100 lines of SQL to do the same" the previous poster mentioned (obviously they were exaggerating a bit and it's less than literally 100 lines, but it's pretty complex).
