E2 - Drop legacy version support (11g, 12c, 18c)[Roadmap]

Scope and goals

Problem

Database versions 11g, 12c, and 18c are no longer supported by Oracle.
utPLSQL should not focus on keeping compatibility with legacy versions. This blocks using newer language/database features elsewhere in this roadmap.

Proposed direction

Remove references to legacy features from 11, 12, and 18. Remove conditional compilation sections. Adjust code to use newer language/database features.

Why first

Removal of compatibility will clean up the code-base, making it easier to move forward with new features and bigger initiatives.
It will also increase the overall safety and stability of the framework and make it easier for the code to remain compliant with enterprise standards and requirements.

Issues tracking

• Decommision support for 11, 12 and 18 databases. utPLSQL#1346
