PSQL PDO SQLSTATE[IM001]:

[taivo1]

I get following error: PDOException: SQLSTATE[IM001]: Driver does not support this function: driver does not support setting attributes.

It occurs when I run codeception tests using Postgres database.
So I tracked down that Postgres PDO driver does not implement ATTR_EMULATE_PREPARES attrbute

Is this still relevant? I can't find those mentioned files.

@nineinchnick I've linked files in original post.

It locks like the problem is the checkIntegrity methode in the postgresql QueryBuilder.

This Methode creates a list of SQL alter table commands and set the ATTR_EMULATE_PREPARES attribute to bypass the postgresql native prepare to fire multiple commands in one.

I test it with PHP7.0 (ubuntu 16.04) and postgresql 9.4 it works without an error.

Seems issue is outdated.
