Hi,
I have just today installed the new version of PostgreSQL (8.1.0), and
my old code seems to have stopped working.
I am basically trying to delete a row from a table:
DELETE FROM "CON" WHERE "ref"='CON5';
I have checked and CON5 is definitively in the CON table. I tried using
JDBC, pgAdminIII and command line but it doesn't seem to work. I get a
message saying 0 rows have been affected, as if the item was not in the
table. Am I doing something wrong? Has the syntax changed or is this
just a bug?
Well, if DELETE had stopped working then 8.1 would never have been
released, so there's something more subtle going on.
1. What happens if you run SELECT * FROM "CON" WHERE "ref"='CON5';
2. What does an "explain analyse" show for that?
3. If it's using an index try: SET enable_indexscan=false; then run
query 1 again.

TIP 9: In versions below 8.0, the planner will ignore your desire to
choose an index scan if your joining column's datatypes do not
match
