Description
- CREATE CONVERSION defines a new encoding
- conversion. Conversion names may be used in the convert function
+ CREATE CONVERSION defines a new conversion between
+ character set encodings. Conversion names may be used in the
+ convert function
to specify a particular encoding conversion. Also, conversions that
- are marked DEFAULT> can be used for automatic encoding conversion between

B and from encoding B to A, must be defined.
