Does anyone know if this feature exists? If so, what version or where
can a patch be obtained?
Thanks

Quoting a recent message by Jan Wieck <janwieck@Yahoo.com>:
:Do a
:
: GET DIAGNOSTICS SELECT PROCESSED INTO <int4_variable>;
:
:directly after an INSERT, UPDATE or DELETE statement and you'll know
:how many rows have been hit.
:
:Also you can get the OID of an inserted row with
:
: GET DIAGNOSTICS SELECT RESULT INTO <int4_variable>;

Apparently you missed Jan's follow-up to my message: "New functionality in
7.1 - sorry." So you'll have to use the beta.

Thank you for clearing that up. I have been searching the mailing list archives, but they seem to be out of date. I could only find my original post and no replies. Of course, my next two questions are: When will 7.1 leave beta (roughly)? How stable is it? FWIW, I'll be using it for development, not production and basically the only feature not in pre 7.1 I'm looking for is the above. -- Dan Langille The FreeBSD Diary - http://freebsddiary.org/ FreshPorts - http://freshports.org/ NZ Broadband - http://unixathome.org/broadband/

From what I've been reading on the lists, "soon". I suspect within the next
month or two.

I've not tested it extensively myself, but it passed my lithmus test (import
a database of a couple of million records in one of its tables, with
numerous constraints and indexes, drop some data based on columns which
aren't indexed, then vacuum it [*]).
HTH,

[*] I've had infinite loops VACUUMing this database under 7.0.3.
