I have problem with new PGSQL 7.1.3
I've a table like that TT ( V VARCHAR(10), D DATE, I INTEGER);
and query "SELECT V || '</TD><TD>' || D || '</TD><TD>' || I FROM TT;"
In version 7.1.2 result is '$V</TD><TD>$D</TD><TD>$I' when $? means text
representation of ?. It's always true even if any $? is NULL.
In version 7.1.3 result is '$V</TD><TD>$D</TD><TD>$I' or NULL if any of
$? is NULL.
Is that change of result intended? (as going to SQL 92?)
