List pgsql-bugs
I have two postgres 7.4.8 databases on hosts X and Y (both P4, running
FC4). I create a table:

   create table test(x int)

I then go into psql and insert a row. Here are the results I'm seeing:

   psql host   postgres host   result
   --------------------------------------
   X           X               crash
   X           Y               OK
   Y           X               crash
   Y           Y               OK

 From the shell running psql, the crash looks like this:

   *** buffer overflow detected ***: psql terminated
   ...

(Full output at the end of this email.)

The databases were created in October, and have been receiving
heavy use. They are vacuumed daily. A few days ago, the database
on X started causing the psql crashes described.

The INSERT actually takes place. If I reconnect and examine the table,
the row is present.

Also, inserts through JDBC work fine and the update count is reported
correctly.

DELETE and UPDATE to the same table do not cause psql to crash, just
INSERT.

I've checked the disks using fsck and badblocks, and found no
problems.

Can anyone suggest what might be going wrong, and what I should
examine next?
