PostgreSQL - Full-Text Search
Why does PostgreSQL allow copying an existing text search configuration instead of modifying built-in ones directly?
ATo enforce licensing restrictions on built-in configs
BBecause built-in configurations are stored in read-only tables
CBecause copying is faster than altering configurations
DTo preserve default configurations and avoid breaking system behavior
Step-by-Step Solution
Solution:

  1. Step 1: Understand purpose of copying configs

    Copying preserves original defaults so system functions remain stable and consistent.

  2. Step 2: Eliminate incorrect reasons

    Built-in configs are not stored in read-only tables; licensing and speed are not relevant reasons.

  3. Final Answer:

    To preserve default configurations and avoid breaking system behavior -> Option D

  4. Quick Check:

    Copying protects defaults and system stability [OK]
Quick Trick: Copy to protect defaults and system stability [OK]
Common Mistakes:
  • Assuming read-only tables prevent changes
  • Thinking licensing restricts edits
  • Believing copying is about speed
