Operating system: OpenBSD
PHP version: 5.2.6
PHP Bug Type: PostgreSQL related
Bug description: pg_escape_bytea + pg_query_params -> malformed data
Description:
------------
OpenBSD 4.1
Apache/1.3.29
php5-core-5.1.6p1
postgresql-client-8.2.4
I want to insert some binary data to a table.
$q = "UPDATE tbl SET data = decode($1, 'base64') WHERE id = $2";
$params = array(base64_encode('binary string'), 123);
$res = pg_query_params($q, $params);
OK
$q = "UPDATE tbl SET data = $1::bytea WHERE id = $2";
$params = array('binary string', 123);
$res = pg_query_params($q, $params);
ERROR: invalid byte sequence for encoding "UTF8": 0x89 HINT: This error
can also happen if the byte sequence does not match the encoding expected
by the server, which is controlled by "client_encoding".
This could possibly work, but does not. Ok, not a problem.
(end of introduction)
Reproduce code:
---------------
# first
$q = "UPDATE tbl SET data = decode($1, 'escape') WHERE id = $2";
$params = array(pg_escape_bytea('binary string'), 123);
$res = pg_query_params($q, $params);
# second
$q = "UPDATE tbl SET data = $1::bytea WHERE id = $2";
$params = array(pg_escape_bytea('binary string'), 123);
$res = pg_query_params($q, $params);
Expected result:
----------------
Be sure to replace 'binary string' with something more challenging!
At least one of these should work (insert the data correctly)
Actual result:
--------------
Both approaches give the same result.
The data gets loaded, but incorrectly.
select length(data) from tbl; -- too large
data contains character sequences like '\000' instead of their values.
btw.
select content = decode(encode(data, 'escape'), 'escape') from tbl; --
works (sequence of TRUEs)
