If polar_comp_redwood_raw_names is set to the default value FALSE, database object names, such as table names, column names, trigger names, program names, and user names, appear in uppercase letters when viewed from Oracle catalogs. In addition, quotation marks enclose names that are created with enclosed quotation marks.

If polar_comp_redwood_raw_names is set to TRUE, the database object names are displayed in the way as they are stored in the PostgreSQL system catalogs when viewed from the Oracle catalogs. Thus, names created without enclosed quotation marks appear in lowercase as expected in PostgreSQL. Names created with enclosed quotation marks appear in the way as they are created, but without the quotation marks.

For example, the following user name is created and then a session is started with that user.

CREATE USER reduser IDENTIFIED BY password;
polardb=# \c - reduser
Password for user reduser:
You are now connected to database "polardb" as user "reduser".        

When you connect to the database as reduser, the following tables are created:

CREATE TABLE all_lower (col INTEGER);
CREATE TABLE ALL_UPPER (COL INTEGER);
CREATE TABLE "Mixed_Case" ("Col" INTEGER);       

When viewed from the Oracle catalog named USER_TABLES, with polar_comp_redwood_raw_names set to the default value FALSE, the names appear in uppercase except for the Mixed_Case name. This name appears in the same way as the name is created and enclosed with quotation marks.

polardb=> SELECT * FROM USER_TABLES;
 schema_name |  table_name 
| tablespace_name | status | temporary 
-------------+--------------+-----------------+--------+-----------
 REDUSER     | ALL_LOWER    |                 | VALID  | N
 REDUSER     | ALL_UPPER    |                 | VALID  | N
 REDUSER     | "Mixed_Case" |                 | VALID  | N
(3 rows)      

When viewed with polar_comp_redwood_raw_names set to TRUE, the names appear in lowercase except for the Mixed_Case name. This name appears in the same way as the name is created, but the name is not enclosed with quotation marks.

polardb=> SET polar_comp_redwood_raw_names TO true;
SET
polardb=> SELECT * FROM USER_TABLES;        
 schema_name | table_name |
tablespace_name | status | temporary 
-------------+------------+-----------------+--------+-----------
 reduser     | all_lower  |                 | VALID  | N
 reduser     | all_upper  |                 | VALID  | N
 reduser     | Mixed_Case |                 | VALID  | N
(3 rows)        

These names match the case when viewed from the PostgreSQL pg_tables catalog.

polardb=> SELECT schemaname, tablename, tableowner FROM pg_tables WHERE
tableowner = 'reduser';
 schemaname | tablename  | tableowner 
------------+------------+------------
 reduser    | all_lower  | reduser
 reduser    | all_upper  | reduser
 reduser    | Mixed_Case | reduser
(3 rows)
