Ok; but what about what I said about the difference between bit/string substring? That affects overlay behaviour for bit... I've even got "ERROR: invalid memory alloc request size 4244635647" with: SELECT substring(B'1111000000000001' from 5 for -2); (this is 8.4.2, windows version, not modified...) test=# SELECT substring(B'1111000000000001' from 1 for -1); substring ------------------ 1111000000000001 (1 row) test=# SELECT substring('1111000000000001' from 1 for -1); ERROR: negative substring length not allowed -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
