Owner with special characters

[gunnareilers]

Issue: Cloning a schema from an owner with special characters causes the clone_schema to fail.

Description: Some statements are executed without quotation marks around the owner.

I quoted the owner at different positions. See diff files for changes that worked for me. diff_clone_schema.sql.txt

Steps to reproduce

• Have a database that belongs to an owner with special characters e.g. "tu-user". Schema, tables, ... belong to that same owner.

• Execute the original code snippet.

• Observe the error due to unescaped special characters.

Diagnostics: line=PL/pgSQL function clone_schema(text,text,cloneparms[]) line 312 at EXECUTE. 42601. syntax error at or near "-"

Proposed change: Add double quotes around the owner in all statements.

Benefits: This change will prevent errors caused by special characters in the owner name.

Thanks a lot!
