SQL error code -601 - Mailing list pgsql-novice

All,

I recevied the SQL error code -601 <ECPG_WARNING_QUERY_IGNORED> from an
embedded C SQL EXEC statement

ie, EXEC SQL DELETE FROM foo WHERE number = 999999;


I've googled the error code, but the only thing I can come up with is
"current transaction is aborted, queries ignored until the end of
transaction block".

Can anybody provide me with a better explanation of what the error means &
what circumstances generate the error?  Is this error just a warning that
can be logged and ignored, or is there a major problem at this point?

Thanks in advance!!
