Log Message:

Update text for RESET CONNECTION:

< all temporary tables, removal of any NOTIFYs, cursors, prepared
< queries(?), currval()s, etc. This could be used for connection pooling.
< We could also change RESET ALL to have this functionality.
> temporary tables, removing any NOTIFYs, cursors, open transactions,
> prepared queries, currval()s, etc. This could be used for connection
> pooling. We could also change RESET ALL to have this functionality.
> The difficult of this features is allowing RESET ALL to not affect
> changes made by the interface driver for its internal use. One idea is
> for this to be a protocol-only feature. Another approach is to notify
> the protocol when a RESET CONNECTION command is used.
