All unquoted identifiers are assumed by PostgreSQL to be lower case by default. This means - SELECT MY_COLUMN FROM my_table - SELECT my_column FROM my_table - SELECT my_column as MY_COLUMN FROM my_table All refer to my_column and has column name in lowercase as my_column.
If the aliases are in upper case and quoted then those are returned in upper case.
- SELECT my_column as "MY_COLUMN" FROM my_table
Is there any workaround to set the alias columns to be returned as upper case without adding quotes. Is there any connection level parameter to flip this behavior?
