GUC Parameter Usage

The database provides many operation parameters. Configuration of these parameters affects the behavior of the database system. Before modifying these parameters, learn the impact of their settings on the database. Otherwise, unexpected results may occur.

Precautions

  • If the value type of a parameter is a string, the string should comply with the naming conventions of the path and file name in the OS running the database.
  • If the allowed maximum value of a parameter is INT_MAX, it indicates that the maximum parameter value varies by OS.
  • If the allowed maximum value of a parameter is DBL_MAX, it indicates the maximum parameter value varies by OS.
