Yeah, but the point I was trying to make is that that's mostly down to
laziness. I see no reason that we couldn't be covering a lot of these
features in src/test/regress/sql/psql.sql, with far less overhead.
The interactive aspects of psql can't be tested that way ... but since
this patch doesn't actually provide any way to test those, it's not much
of a proof-of-concept.
IOW, the blocking factor here is not "does src/bin/psql/t/ exist",
it's "has somebody written a test that moves the coverage needle
meaningfully". I'm not big on adding a bunch of overhead first and
just hoping somebody will do something to make it worthwhile later.
