PostgreSQL – How to Rename a Sequence

ByAdmin

You can rename a sequence using the ALTER SEQUENCE statement with the RENAME TO clause in PostgreSQL database. Here’s the basic syntax for renaming a sequence:

ALTER SEQUENCE old_sequence_name RENAME TO new_sequence_name;

where old_sequence_name is the current name of the sequence you want to rename, and new_sequence_name is the new name you want to assign to the sequence.

Please note that when you rename a sequence, it does not impact the objects (such as tables) that use the sequence. You may need to update those objects manually to use the new sequence name if necessary.

Be cautious when renaming sequences, especially if they are used by other database objects, to avoid breaking dependencies in your database.
