Would the inclusion of the entire directory be done via a single #include (or whatever syntax) directive in
pg_hba.conf?

I think that's probably OK. But if we're talking about something like "hey, if there's a pg_hba.d directory then
magicallyslurp that in", that's far less useful and a much bigger foot-gun. (It also wouldn't provide any value for
whatJerry (the op) needs).
 


To summarize, here's what I've seen on this discussion:

- People seem to generally be in favor of the idea of "includes", though it's not completely clear if people want
specific"include file X at this point in the ruleset" or something more nebulous.
 
- It would be useful to have a mechanism for testing a pg_hba.conf file.
- It would also be useful for denied connections to log the actual line/file that denied the connection.
- This would be a good GSoC project.
