This has nothing to do with PHP, really, though obviously there can be
workarounds for this in connection libraries. In PostgreSQL column
names are translated to lower case unless they are not enclosed in
double-quotes like "column_name". In Oracle column names are translated
to upper case unless they are quoted.

So one answer would be to explicitly specify the case of the column and
to always refer to it in your SQL in double-quotes.

You should probably use PDO, which has always seemed to be the closest
PHP comes to DBI, and look at using the "PDO_CASE_UPPER" flag on
connecting to the database. This may do what you want.
