This is what bothers me about this whole exercise - it is addressed to
our particular storage method for this stuff. That's analogous to us
having to address tuples in pages directly, rather than using a higher
level abstraction like SQL. Ideally, any API would adapt to us changing
the storage methods completely (say by putting the info in tables)
without any change being necessary in the clients. That goes for the
config file as well as the hba file, although the hba file case is
harder because order is much more important.
Incidentally, I thought I had voiced some similar concerns some time ago
- I certainly know I have had them for a while - if I am late in
expressing them then I apologise. I would just hate to see us adopt a
bad solution now that would make moving to a good solution later much
