Add support for metadata of PostgreSQL UUID column type

[yruslan]

Background

PostgreSQL has UUID column type. When Pramen loads the schema, metadata of varchar(n) fields is extracted as maxLength metadata key. But for UUID this is not happening, so the resulting data type is just string.

Feature

Add support for metadata of PostgreSQL UUID column type.

Example [Optional]

Proposed Solution [Optional]

Need to investigate if it is possible to get the metadata information for UUID columns in the first place
