## What changes were proposed in this pull request?
This PR is to port numeric.sql from PostgreSQL regression tests. https://github.com/postgres/postgres/blob/REL_12_BETA2/src/test/regress/sql/join.sql
The expected results can be found in the link: https://github.com/postgres/postgres/blob/REL_12_BETA2/src/test/regress/expected/join.out
When porting the test cases, found eight PostgreSQL specific features that do not exist in Spark SQL:
