Looks like you didn't get me, am not saying aliases to be all upper case by

code, much of which isn't even under our control. The margina

Note that adding quotes for aliases will be blessed by PostgreSQL and
then those will be folded to upper case BUT this adds up to lot of
changes in the SQL layer.
I wonder why you need that. I never had the requirement for that.

sorry, but you misunderstand. this is the correct behavior of SQL.
It is part of the specification to do this.

Thanks!
Sure this is not a bug. Just want to know if there is any possible way to
achieve this.
Reason being - need to change all the data layer of project where the
column mapping has been done with Upper Case.

Hello,
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.
