What you describe Tom (flat file), sounds a bit strange to me.
Aren't users
stored in a table? (pg_catalog.pg_authid)
Yeah, but the postmaster can't read pg_authid, nor any other table,
because it's not logically connected to the database. So any change
to pg_authid gets copied to a "flat" ASCII-text file for the
postmaster.
Why doesn't the postmaster read the db files directly, presumably
using some of the same code the backends do, or is too hard to bypass
the shared memory layer? Another thing you folks must have
considered would be to keep the out-of-memory copies of this kind of
data in something faster than a flat file - say Berkeley DB. Do
either of these things make sense?
