I am looking for a way to obtain the words that are common amongst two tsvector records. The long workaround I know is to: 1)convert the contents of the tsvector fields to text then find and replace single quote followed by space then single quote with a comma character then stripping away the first and last single quote characters. 2)convert this CSV data into array using string to array. 3)Perform a join on these two arrays and unnest them and join on the unnested values. 4)Perform array_agg on any one field (of unnested array values) of these two tables with aid of a GROUP BY. 5)cast the array to string using a white space as the delimiter. 6)cast the string to tsvector.
