Thanks for the patch!
-DATA = postgres_fdw--1.0.sql
+DATA = postgres_fdw--1.1.sql postgres_fdw--1.0--1.1.sql
Shouldn't we leave 1.0.sql as it is and create 1.0--1.1.sql so that
we can run the followings?
CREATE EXTENSION postgres_fdw VERSION "1.0";
ALTER EXTENSION postgres_fdw UPDATE TO "1.1";
+<sect2>
+ <title>Functions</title>
The document format for functions should be consistent with
that in other contrib module like pgstattuple?
+ When called in the local session, it returns an array with each element as a
+ pair of the foreign server names of all the open connections that are
+ previously made to the foreign servers and <literal>true</literal> or
+ <literal>false</literal> to show whether or not the connection is valid.
We thought that the information about whether the connection is valid or
not was useful to, for example, identify and close explicitly the long-living
invalid connections because they were useless. But thanks to the recent
bug fix for connection leak issue, that information would be no longer
so helpful for us? False is returned only when the connection is used in
this local transaction but it's marked as invalidated. In this case that
connection cannot be explicitly closed because it's used in this transaction.
It will be closed at the end of transaction. Thought?
I guess that you made postgres_fdw_get_connections() return the array
because the similar function dblink_get_connections() does that. But
isn't it more convenient to make that return the set of records?
