Have you considered using different schema for this purpose? This is an extra layer that PostgreSQL has which is different than other RDBMs. -- Michael

PostgreSQL version: 9.4.0

Description:
I try to create view using involve columns from multiple databases.
then i have issue postgresql cross database reference are not implemented.
how to resolve that issue
This is a question better suited to the -general list as it is not a bug report.
If you are indeed using 9.4.0 you need to upgrade to a supported release - which is 9.4.16 at the time of this report.
In addition to Michael's suggestion of using schemas you might be able to make use of postgres_fdw
Work on that area has been ongoing recently and if you go for that approach you should probably strongly consider bumping up to version 9.6 or 10. 9.4 has a little over a year of support-life left in it anyway.
