Re: BYTEA data type

Unfortunately, 7.2 (current development) version docs are not online, and
current relased version (7.1.2) doesn't have it documented.


Bytea just stores a chunk of data. The difference between bytea and blobs
is that you cannot manipulate small chunks of bytea data currently, entire
bytea data must be extracted. (If you have 1-G long string in a bytea
column, and you only need first 8K bytes, entire string must be retrieved
first). If that's not a problem for you, use bytea.

There are some rules on escaping of bytea data. Do a search on
http://fts.postgresql.org for 'bytea escaping' for details.
