It appears the getBytes was previously being used to return a byte array
of any arbitrary column.

Fixes for blobs seem to have broken this. The question is as Jason
pointed out which do we fix.

It doesn't seem unreasonable to be able to return a byte array for any
arbitray column. On the other hand is this the intended use?

Hi,

There seems to be a problem with DatabaseMetaData.getTables() when I do
the following:

ResultSet R=conn.getMetaData().getTables(null, null, "%", null);

It throws a NullPointerException:

java.lang.NullPointerException
    at
org.postgresql.jdbc2.DatabaseMetaData.getTables(DatabaseMetaData.java:17
32)
    at Test.main(Test.java:66)

Looking at the source, ResultSet.getBytes() is called and it returns
null, causing this exception to be thrown. However I can use
ResultSet.getString() without a problem. I'm using 7.1.3 at the moment.
Does ResultSet.getBytes() need to be fixed or should getTables() be
modified?

I'd be grateful for any insights. Or you can just tell me to use the
latest cvs version of PostgreSQL :) What is the consensus on supporting
older versions, will you phase out old code when 7.2 comes out?
