One more question regarding dblink

Hi,

I know I should have clubbed in last post but did not notice.

1. Why is that dblink allows only one persistent connection? It should allow 
more than one persistent connections to same or different databases, 
searchable by name. Of course we do not expect number of remote connection to 
be huge. So a simple structure would suffice.

2. To create a persistent connection, one has to call dblink_connect 
explicitly. Oracle allows a database link connection to be part of database 
schema. Hence when a database comes up it brings the database link up as 
well.

Is there an equivalent of .profile/.logout  per database/per schema/per table 
in postgresql? That should be an ideal place to put a database link 
initiation/termination.

Should be a nifty addtion. I don't know how practical that sounds to core 
developers.
