Convert OGC Filter's literals accordings to field type. This can have a huge impact on performance in some cases. For example for a filter like "num_char" = '+2' converted to "num_char" = 2, this result with PostgreSQL provider in a fallback to client side evaluation for the whole filter, including the bbox if present.
