[Fix][Doc] Delete space before _test and _sink

[kehan-zhou]

Purpose of this pull request

This pull request fixes formatting issues in the PostgreSQL documentation where a space was mistakenly added before suffixes like _test and _sink in example table names.
Examples fixed:

• ${schema_name}.${table_name} _test → ${schema_name}.${table_name}_test
• dbo.tt_${table_name} _sink → dbo.tt_${table_name}_sink

This improves accuracy and consistency in documentation.

Related Issue: Fixes #9214
