Bug description:pg_escape_bytea returns a format different from the expectation
Description:
------------
Using PostgreSQL 9.0.1, pg_escape_bytea function returns new "hex" format.
By defaults, PostgreSQL outputs new "hex" format for bytea data.
It is possible to change to "escape" format by modifying the
postgresql.conf file.
I expecting the test script displays "AAA" always.
However, pg_escape_bytea actually returns a different ("hex") format while
the database is connected.
After disconnected, pg_escape_bytea returns correct ("escape") format.
Test script:
---------------
<?php
$link = pg_connect('dbname=template1 user=postgres');
$version = pg_version($link);
print "PostgreSQL version information\n";
var_dump($version);
$result = pg_query($link,"show bytea_output");
$col = pg_fetch_row($result,0);
pg_free_result($result);
print "environment variable: bytea_output\n";
var_dump($col);
print "pg_escape_bytea('AAA') before database connection closing\n";
print pg_escape_bytea('AAA')."\n";
pg_close($link);
print "pg_escape_bytea('AAA') after database connection closing\n";
print pg_escape_bytea('AAA')."\n";
Expected result:
----------------
PostgreSQL version information
array(3) {
["client"]=>
string(5) "9.0.1"
["protocol"]=>
int(3)
["server"]=>
string(5) "9.0.1"
}
environment variable: bytea_output
array(1) {
[0]=>
string(6) "escape"
}
pg_escape_bytea('AAA') before database connection closing
AAA
pg_escape_bytea('AAA') after database connection closing
AAA
Actual result:
--------------
PostgreSQL version information
array(3) {
["client"]=>
string(5) "9.0.1"
["protocol"]=>
int(3)
["server"]=>
string(5) "9.0.1"
}
environment variable: bytea_output
array(1) {
[0]=>
string(6) "escape"
}
pg_escape_bytea('AAA') before database connection closing
\\x414141
pg_escape_bytea('AAA') after database connection closing
AAA
