Why would you think it would take that?  The manual says that lines
beginning with '#' are comments, but not more than that.

https://www.postgresql.org/docs/current/libpq-pgpass.html

I searched the man page for "#" and "comment".  The only mention is in this sentence:

[quote]
hostname:port:database:username:password
(You can add a reminder comment to the file by copying the line above and preceding it with #.)
[/quote]

That one sentence can easily be read as only referring to the "hostname:port..." line.

Since postgresql.conf and pg_hba.conf (I don't use pg_ident.conf) allow trailing comments,  it seems reasonable that .pgpass should too, for consistency.

It also seems reasonable that hostnames in .pgpass should be case-insensitive, since they're case-insensitive everywhere else in the network world.

If that acted as a comment, it'd be impossible to use passwords
containing '#'.

Escapes.  It escapes ":" and "\", so should be able to escape "#".
