Thanks for your attention to this.
I'm definitely not a cryptography expert, but it seems to me that the
actual mechanisms (MD5, SHA-256) are more important than the protocols used
to negotiate them (SASL, SCRAM). When some security expert unfamiliar with

Hi all,
range_intersect_agg is documented to return anymultirange (on this
page[1]), but it actually returns a range.
In addition, range_intersect_agg also accepts a multirange as its
parameter, but that's not documented on the same page. Note that range_agg
does *not* accept a multirange (possib
Hi all,
The PostgreSQL docs mostly show function names in lowercase (e.g. [1],
[2]), which seems to be the PostgreSQL-idiomatic thing to do. However, some
pages show functions in upper case, e.g. COALESCE/NULLIF/GREATEST/LEAST
([3]). Is there some difference between these which warrants the case

Thanks. Yeah, I noticed that comment, but NULLIF which is also documented
on that page isn't mention
