Обсуждение: Re: [COMMITTERS] pgsql-server: Make listen_addresses be a comma-separated

Hey Tom,

If you've just made this a GUC_LIST_INPUT variable, then you will need 
to update the nasty bit of hackiness in pg_dumpall to allow it to be 
dumped without error :(

It's line 782 of pg_dumpall.c.  I wonder if you will like that code once 
you look at it :P

The problem is there's no way to know if they're list type gucs when 
dumping, unless we modify the pg_settings view or something.

Dumped by what?  It's a PGC_POSTMASTER variable, there ain't gonna be
nobody putting it in ALTER DATABASE or ALTER USER.

Yeah, it might be nice to have an API to get at those flag bits.

Oh yeah, sorry wasn't thinking.  Same reason I don't bother handling 
preload_libraries and friends in pg_dumpall...

Will become more annoying once we have a binary dump format for 
pg_dumpall I guess, have to store them in the binary.
