... Because it represents information that needs to be accessed
*before* a connection to the database is established.

This is the configuration that determines whether or not a DB
connection is permitted. If we store the information in a table, then
the connection has to be accepted in order to determine if the
connection should be accepted.

As things stand, pg_hba.conf will reject many of the cases without
needing to burden the database engine with another connection.

If connections are required, then:

a) There are presumably some new race conditions for vulnerabilities
that come available;

b) A new DOS attack is introduced.
