Copy json from couchbase to postgres

[Rushikesh socha <rushikesh.s@xxxxxxxxx>]

Any suggestions on copying .json which is exported from couchbase using cbexport json. I used copy command but most of them are throwing error.

pgdocstore=# copy schaname.tablename from 'path/filename.json';
ERROR:  invalid input syntax for type json
DETAIL:  Token "H" is invalid.
