I've just added some code to explain.c to change the label of join nodes
when they are using special join rules (for outer joins or IN joins).
This wasn't all that interesting up through 7.3, because knowing the
query you could be quite sure which join rule was in effect at each
step. But now
The recent addition of drop column makes possible to change column type.
E. g. : I have written a small utility reading Medline queries results and
dumping them in a Postgres database for further analysis.

and that you

Erm, perhaps not, but you can use it as the link step (both to
generate executables and to generate shared objects) on many systems.
Hi guys,
Looking at the log_duration postgresql.conf option. How about adding an
option log_duration_min which is a value in milliseconds that is the minimum
time a query must run for before being logged. Basically, what I'd be
interested in is please log the SQL query and duration of all

So you put the MD5 sum into the release announcement email. That is

Fine with me --- but you'll need to add more
Hi,
In the merge join as well as in the nested loop join,
we do ExecProject() after we have found tuples from
the relations involved in the join.
For a join query involving just two relations and
merge join being used, the outer plan will be
NodeSort. Now, NodeSort will create Temp files and

I can't see any security rationale for restricting it.
The language on the frontend is the same as the one used for the server

why would PUBLIC have any?
