WMS_Increase the size of rasql fragment query in varchar

[Bang Pham Huu]

current WMS 1.3 only set rasql fragment to varchar(255), it should be set larger or have error

Mar 22 12:56:34 xx server[1490]: DEBUG [12:56:34] BaseMappedStatement@41: insert data with statement 'INSERT INTO "wms13_style" ("name" ,"title" ,"styleAbstract" ,"legendURL_id" ,"rasqlQueryTransformer" ,"layer_id" ) VALUES (?,?,?,?,?,?)' and 6 args, threw exception: 

org.postgresql.util.PSQLException: ERROR: value too long for type character varying(255)

also, update_petascopedb.sh needs to run a psql command to update existing petascopedb.

e.g: change to 2000 characters.

psql -U postgres petascopedb -c 

'ALTER TABLE wms13_style ALTER COLUMN "rasqlQueryTransformer" TYPE varchar (2000);'
