New Comment:
When you issue queries that change the database session environment
like that, PDO has no way to know what you've done without performing
all kinds of checks on each query.
There's no reason to slow down the common case for everyone else.
All your problems are solved by using real prepared statements, where
explicit quoting is not required.

Description:
------------
I'm running MySQL in ANSI SQL mode [1], which includes the ANSI_QUOTES
mode. That means
/Treat " as an identifier quote character (like the ` quote
character) and not as a string quote character./
When I use ie. prepared statements I get these queries in the general
query log
INSERT INTO "t_images" ("hash", "width", "height", "imageformat_id")
VALUES ("ff2204530628d3c589843ef0b37d344a", "500", "500", NULL)
Which is bad, the strings (the hash) in the VALUES (...) section should
be quoted by the ' character. Don't know what would be the best
solution, but I think some documented MySQL specific PDO attribute
would be Ok.
Thanks for reviewing this issue.
