DROP TABLE Fails to Be Executed

Problem

DROP TABLE fails to be executed in the following scenarios:

  • A user runs the \dt+ command using gsql and finds that the table_name table does not exist. When the user runs the CREATE TABLE table_name command, an error message indicating that the table_name table exists is displayed. When the user runs the DROP TABLE table_name command, an error message indicating that the table_name table does not exist is displayed. In this case, the table_name table cannot be recreated.
  • A user runs the \dt+ command using gsql and finds that the table_name table exists in the database. When the user runs the DROP TABLE table_name command, an error message indicating that the table_name table does not exist is displayed. In this case, the table_name table cannot be recreated.

Possible Causes

The table_name table exists on some nodes only.

Troubleshooting Method

In the preceding scenarios, if DROP TABLE table_name fails to be executed, run DROP TABLE IF EXISTS table_name to successfully drop table_name.
