pq10522.st  REUSING CACHED CURSOR DOES NOT SET DATA LENGTH CORRECTLY

Reusing a cached cursor that initially had a null value for a parameter marker 
or host variable in an AbtDatabaseFixedCharField and subsequently used for a 
non-null data value will result in the length of that field getting set incorrectly.
