Exotic Features
|
||||
===============
|
||||
|
||||
* Add pre-parsing phase that converts non-ISO syntax to supported
|
||||
syntax
|
||||
|
||||
This could allow SQL written for other databases to run without
|
||||
modification.
|
||||
|
||||
* Allow plug-in modules to emulate features from other databases
|
||||
* SQL*Net listener that makes PostgreSQL appear as an Oracle database
|
||||
to clients
|
||||
* Allow statements across databases or servers with transaction
|
||||
semantics
|
||||
|
||||
This can be done using dblink and two-phase commit.
|
||||
|
||||
* Add the features of packages
|
||||
|
||||
o Make private objects accessible only to objects in the same schema
|
||||
o Allow current_schema.objname to access current schema objects
|
||||
o Add session variables
|
||||
o Allow nested schemas
|
||||
|
||||
* Consider allowing control of upper/lower case folding of unquoted
|
||||
identifiers
