23 years agoRestructure index AM interface for index building and index tuple deletion,
Tom Lane [Sun, 15 Jul 2001 22:48:19 +0000 (22:48 +0000)]
Restructure index AM interface for index building and index tuple deletion,
per previous discussion on pghackers.  Most of the duplicate code in
different AMs' ambuild routines has been moved out to a common routine
in index.c; this means that all index types now do the right things about
inserting recently-dead tuples, etc.  (I also removed support for EXTEND
INDEX in the ambuild routines, since that's about to go away anyway, and
it cluttered the code a lot.)  The retail indextuple deletion routines have
been replaced by a "bulk delete" routine in which the indexscan is inside
the access method.  I haven't pushed this change as far as it should go yet,
but it should allow considerable simplification of the internal bookkeeping
for deletions.  Also, add flag columns to pg_am to eliminate various
hardcoded tests on AM OIDs, and remove unused pg_am columns.

Fix rtree and gist index types to not attempt to store NULLs; before this,
gist usually crashed, while rtree managed not to crash but computed wacko
bounding boxes for NULL entries (which might have had something to do with
the performance problems we've heard about occasionally).

Add AtEOXact routines to hash, rtree, and gist, all of which have static
state that needs to be reset after an error.  We discovered this need long
ago for btree, but missed the other guys.

23 years agoThe attached patch fixes problems with the JDBC driver handling long
Bruce Momjian [Sun, 15 Jul 2001 04:21:26 +0000 (04:21 +0000)]
The attached patch fixes problems with the JDBC driver handling long
null terminated strings.  The FE/BE protocol sends in some cases null
terminated strings to the client.  The docs for the FE/BE protocol state
that there is no limit on the size of a null terminated string sent to
the client and a client should be coded using an expanding buffer to
deal with large strings.  The old code did not do this and gave an error
if a null terminated string was greater than either 4 or 8K.  It appears
that with the advent of TOAST very long SQL statements are becoming more
common, and apparently some error messages from the backend include the
SQL statement thus easily exceeding the 8K limit in the old code.

In fixing I also cleaned up some calls in the JDBC fastpath code that
were not doing character set conversion under multibyte, and removed
some methods that were no longer needed.  I also removed a potential
threading problem with a shared variable that was being used in
Connection.java.

Thanks to Steve Wampler for discovering the problem and sending the
initial diffs that were the basis of this patch.

Prohibit a column from appearing twice in a PRIMARY KEY or UNIQUE

(c) is certain to cause a failure downstream when we try to create

immediately, we will fork a child even if the database state does not
