GUC Parameter Usage

Updated at: Mar 13, 2020 GMT+08:00

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 these parameters on the database. Otherwise, unexpected results may occur.

Precautions

  • If the value range 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 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.
