< o Add ALTER TABLE tab ADD/DROP INHERITS parent
<
< This allows tables to be added/removed from an inheritance
< hierarchy. This is particularly useful for table partitioning.

> o -Add ALTER TABLE tab INHERIT / NO INHERIT parent
< o Add support for WITH HOLD cursors
> o Add support for WITH HOLD and SCROLL cursors
>
> PL/pgSQL cursors should support the same syntax as

< o Add new version of PQescapeString() that doesn't double backslashes
< that are part of a client-only multibyte sequence
<
< Single-quote is not a valid byte in any supported client-only
< encoding. This requires using mblen() to determine if the
< backslash is inside or outside a multi-byte sequence.

< o Add new version of PQescapeString() that doesn't double
< backslashes when standard_conforming_strings is true and
< non-E strings are used
