I tell it that I'm using <database and version> and give it the relevant DDL statements (e.g. CREATE TABLE, etc) then ask it to write the query to do <x> in plain English. It does surprisingly well.

But!!! the first response is rarely dead-on and instead, just like a junior eng I need to guide it: use (or don't use) SQL construct <x>, make sure to use index <x>, etc.

Example: to sum the values in a JSONB field, GPT desperately wanted to use a lateral join but that would have made for a very awkward set of VIEWs. So instead I directed it to create a function to perform the summation.
