I'm looking for any guides on how to escape SQL correctly in a program. What I'd really like is something like placeholders, where I could do

$escaped_sql = escape_with_placeholders( "INSERT INTO foo VALUES ( ?, 
+?, ? )", $a, $b, $c );

The database I'm using is Postgres, although I'd like to stay as agnostic as possible. I'm sure DBI has some way to do this, but I can't work out how I would go about creating a DBI object without a database to connect to, or how I would intercept the escaped SQL. The data I'll be needing to escape includes random bytes than can span the entire 0-255 range, and it needs to make it into the database without error or corruption.
