Document LOB datatype in Reference manual

Create,Insert,Update SQL syntaxes need to be documented in the Reference manuals. Some of these are for use by JDBC only. So we may want to document the JDBC interfaces alone for those.
So in the document below, any syntax that takes in "buffer" input should be left out of the SQL reference manual since it's an interface meant for JDBC driver use only. The document contains a comment saying "Internal use only" for any syntax that shoudl not be documented in the reference manual.
The JDBC documentation should however cover all cases.
