[HACKERS] bug with current sources? Re: cost of parse/plan/execute for onesample query

2002-04-13 Thread Barry Lind
In testing Neil's PREPARE/EXECUTE patch on my test query, I found the parser complains that this query is not valid when using current sources. The error I get is: psql:testorig.sql:1: ERROR: JOIN/ON clause refers to "xf2", which is not part of JOIN I think the sql is valid (at least it has

Gavin, I will do the legwork on this if you wish. I think we need to use DefElem to store the COPY params, rather than using specific fields in CopyStmt. Would you send me your original patch so I am make sure I hit everything. I can't seem to find a copy. If you would like to work on it, I c

David, sorry you patch didn't make it into 7.2.X. That whole EINTR discussion was quite complicated so I am not surprised we missed it. The attached patch implements your ENITR test in cases that seems to need it. I have followed the method we used for ENITRY in fe-misc.c. --

In benchmarks that I have done in the past comparing performance of Oracle and Postgres in our web application, I found that I got ~140 requests/sec on Oracle and ~50 requests/sec on postgres. The code path in my benchmark only issues one sql statement. Since I know that Oracle caches query p

Can someone please fix this? Building JDBC staffs in current has been broken for a while(7.2.x is ok). Maybe current JDBC build process requires more recent version of ant than I have, I don't know. But if so, that should be stated somewhere in the docs explicitly, I think. /usr/bin/ant -buildfil
