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***
functions, *not* WinSock. We need to look for a workable solution for
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.

where rightmost index page splits while we are waiting to obtain exclusive
lock on it. Not clear this would actually hurt (probably the callback
would always fail), but better safe than sorry.
Also, improve comments describing concurrency considerations in this code.
