i need to fech each post, parse for expressions and replace with other.
But now i see that post_text is BLOB and there is a post_checksum field and i think if i modify something to post_text content, there will be trouble.
Also i saw that is possible to convert binary blob field into text with CONVERT(column USING utf8), but after i parse and replace post_text with the new content, the checksum will be incorect.
Is it possible to do this changes?
(Excuse my bad english)
