- Fixed bug in ecpglib causing indicator to list the size of the
variable instead of the size of the data.
to use and significantly faster. This tweak saves 25% (!) of the runtime
of COPY IN in a test with 8000-character lines. I wouldn't normally
commit a performance improvement this late in the cycle, but 25% got
my attention...
the latest version and I wanted to make sure that there was a clean release.
I also change the build files as I discussed in my letter of Nov 6, 2001. At
the time I was asked to hold off until after the release.
Magnus Hagander that DLL only contains error strings for the Net***

older Windows flavors ... but it won't happen for PG 7.2.
to give more useful error messages. Stephen Szabo's example of this
morning ('loop' used as a variable name inside a subselect) works
correctly now, and a FOR that is misinterpreted as an integer FOR will
draw 'missing .. at end of SQL expression', which is at least
marginally helpful.
remove brain-dead rule that double quotes are needed if and only if the
datatype is pass-by-reference; neither direction of the implication holds
water. Instead, examine the actual data string to see if it contains
any characters that force us to quote it.
Add some documentation about quoting of array values, which was previously
explained nowhere AFAICT.
never did inflateEnd, thus leaking some tens of KB per call. Which
added up *real fast* when dealing with, say, thousands of BLOBs.
Thanks to Lane Rollins for the bug report.
per bug report from Stefan Hadjistoytchev. There are some cases
where the dot notation works, but there are more where it doesn't.
Eventually ought to consider fixing the parser to allow cases like
func().field, but for now this is the simplest patch.
The bug was that any insert or update would fail if the returned oid was
larger than a signed int. Since OIDs are unsigned int's it was
a bug that the code used a java signed int to deal with the values. The bug
would result in the error message: "Unable to fathom update count".
While fixing the bug, it became apparent that other code made a similar
assumption about OIDs being signed ints. Therefore some methods that returned
or took OIDs are arguements also needed to be changed.
Since we are so close to the 7.2 release I have added new methods that
return longs and deprecated the old methods returning ints. Therefore all
old code should still work without requiring a code change to cast from long to int. Also note that the methods below are PostgreSQL specific extensions to
the JDBC api are are not part of the spec from Sun, thus it is unlikely that
they are used much or at all.
The deprecated methods are:
ResultSet.getInsertedOID()
Statement.getInsertedOID()
Serialize.store()
Connection.putObject()
and are replaced by:
ResultSet.getLastOID()
Statement.getLastOID()
Serialize.storeObject()
Connection.storeObject()
All the deprecated methods returned int, while their replacements return long
This patch also fixes two comments in MD5Digest that the author Jeremy Wohl
submitted.

would always fail), but better safe than sorry.

search lists was broken in such a way that only the most recent
instance of a given hash code would ever be searched, thus possibly
missing longer matches further back. Fixing this gave 5 to 10%
compression improvement on some text test cases. Additional small
tweaks to improve speed of inner loops a little bit. There is no
compatibility issue created by this change, since the compressed data
format and decompression algorithm don't change.
This seems the right thing for most usages, but I notice two places
where it is the wrong thing. One is that the default permissions on
TOAST rels should be no-access, not world-readable; the other is that
PrepareForTupleInvalidation doesn't really need to spend time looking
at tuples of TOAST relations.
int8, int16, int32, int64 and separately uint8, uint16, uint32, uint64
The previous patch grouped:
int8, int16 and int32
uint8, uint16 and uint32
int64 and uint64 <-- this grouping is wrong on AIX 4.3.3 and below
If you prefer to make 4 groups out of this you could apply this patch.

There's also a little fix for the getRow() method. While fixing
absolute(), I noticed that getRow() wasn't quite following the spec: it
wasn't returning 0 when the ResultSet wasn't positioned on a row. I've
started a ResultSet test case and included it as well.
