the JDBC driver.
This method is currently unimplemented and always returns
ResultSetMetaData.columnNullable. This is obviously incorrect
when a column is defined with NOT NULL or PRIMARY KEY. And we
have to think of check constraints, views, functions etc.
The patch simply changes the return value to
ResultSetMetaData.columnNullableUnknown. This is until someone
comes up with a real implementation of course.

by escape processing in the SQL statement. I've tested this for a
while now and it appears to work well. Previously string data
with {d was getting corrupt as the {d was being stripped regardless
of whether it was an escape code or not.
I also added checking for time and timestamp escape processing strings
as per 11.3 in the specification. The patch is against the latest
CVS.

under libdir, for a cleaner separation in the installation layout
and compatibility with binary packaging standards. Point backend's
default search location there. The contrib modules are also
installed in the said location, giving them the benefit of the
default search path as well. No changes in user interface
nevertheless.

Here's rev 2 of the bytea string support patch. Changes:
1. Added missing declaration for MatchBytea function
2. Added PQescapeBytea to fe-exec.c
3. Applies cleanly on cvs tip from this afternoon
I'm hoping that someone can review/approve/apply this before beta starts, so
I guess I'd vote (not that it counts for much) to delay beta a few days :-)

I agree that this is a problem, though it is not possible to do
anything harmful with it. In addition, it only occurs if there are
any NUL characters in its input, which is very unlikely if you are
using C strings.
The patch below addresses the issue by removing escaping of \0
characters entirely.

We can't do that, this would require 4n + 1 bytes of storage for the
result, breaking the interface.
