Comment:

 Replying to [comment:34 maythamalsudany]:
 > What is the purpose of `SELECT $prefix` in wp-admin/setup-
 config.php:317?

 The purpose is to disallow table prefixes that would cause a syntax error,
 see [37581] / #36422.

 There is some more context in comment:20:
 > We want this error to be triggered (it proves that it's an appropriate
 table prefix), but we don't want it to be displayed at all.

 [41631] / #40655 was supposed to silently discard the error, but appears
 to not always work as expected.

 [attachment:"42362.2.diff"] refreshes the patch, testing would be
 appreciated.
