This is Postgresql 8 RC 1 on freebsd 5.3.
I changed the type of a column from varchar(128) to varchar(256), and
right after that I got the following messages when doing inserts on
the table in question.
<41e0e2c3.fd54>ERROR: SMgrRelation hashtable corrupted
<41e0e2c3.fd54>STATEMENT: commit

<41e0e2c3.fd54>WARNING: StartTransaction while in START state
<41e0e2c3.fd54>WARNING: there is no transaction in progress
These went on for a few queries, then stopped and I then started getting this:
<>ERROR: could not open relation 1663/17231/126958: No such file or directory
<>CONTEXT: writing block 2919 of relation 1663/17231/126958

<>WARNING: could not write block 2919 of 1663/17231/126958
<>DETAIL: Multiple failures --- write error may be permanent.
I then ran vacuum and got this message, and after that the errors stopped:
WARNING: relation "cart_groups" page 1 is uninitialized --- fixing
Somewhere along the line postgres dumped core once and this is the backtrace:
