Subject: [PATCH v2 1/2] Built-in compression method

Add syntax allowing a compression method to be specified.
As of now there is only 2 option for build-in compression
method (pglz, zlib) which can be set while creating a table
or adding a new column.  No option for altering the
compression method for an existing column.
