PostgreSQL Error 2200H: Sequence Limit Exceeded
Description
This `Data Exception` (error class 22) occurs when a PostgreSQL sequence generator attempts to generate a new value that exceeds its defined maximum or minimum limit. It typically happens when the sequence has been exhausted and is configured not to cycle, preventing further ID generation.
Error Message
sequence generator limit exceeded
Known Causes
4 known causesSequence Reached Max Value
The sequence has generated values up to its predefined maximum limit (e.g., `MAXVALUE` or the maximum value of its underlying data type).
Insufficient Data Type
The data type chosen for the sequence (e.g., `SMALLINT` or `INT`) is too small for the anticipated number of generated values over the database's lifespan.
Sequence Defined NO CYCLE
The sequence was created with the `NO CYCLE` option, meaning it will not restart from its minimum value after reaching its maximum, leading to this error.
Rapid ID Generation
A high volume of insertions or operations requiring new sequence values quickly consumed the available sequence range, leading to premature exhaustion.
