No mysqlnd-libmysql BC break here.
Metadata and libmysql - there's hardly a better example why mysqlnd
should be set as a default. With libmysql as a default, PHP 5.4 will
have a "randomly" crashing default configuration.

(Note how the issue is there, then gone and then back again depending on
version...)

EXPLAIN - metadata [ext/mysqli/tests/mysqli_explain_metadata.phpt]
The reason is that plain SQL and prepared SQL return different data -
catalog field sometimes is "def", sometimes NULL in MYSQL_FIELD
structure returned by mysql_fetch_field_direct(). It may be mysql bug in
which case test should be SKIPed for versions that have this bug.
And, yet again metadata...
PASS EXPLAIN - metadata [ext/mysqli/tests/mysqli_explain_metadata.phpt]
libmysql 5.1.49 @ MySQL 5.1.49
libmysql 5.5.15 @ MySQL 5.1.49
libmysql 5.6.2-m5 @ MySQL 5.1.49
mysqlnd @ MySQL 5.1.49
mysqlnd @ MySQL 5.1.37
FAIL
libmysql 5.1.37 @ MySQL 5.1.37
... always use the latest and greatest. Libmysql bug, exact version
range is not known to me. Feel free to change the test to be skipped
during SKIPIF, for example, like this:
require(connect.inc)
if (!IS_MYSQLND && libmysql_version > ... && libmysql_version < ...)
die(skip libmysql bug)
At the first look, I can't find a related bug report at bugs.php.net.
Looks like few people compare PS and non-PS metadata for EXPLAIN in
their application.
