Question

I’m having some trouble with my application. It works in my development environment but not on my customers server..

The generate_series with timestamps does not work. The same function but with integers work.

Error message:

 [Request processing failed; nested exception is javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: could not execute query] with root cause
    org.postgresql.util.PSQLException: ERROR: function generate_series(unknown, unknown, interval) does not exist
      Hint: No function matches the given name and argument types. You might need to add explicit type casts.

I can’t locate the function in PostgreSQL. Where can I get a copy of these methods so I can install them if possible.

Answer 1

You don’t mention your PostgreSQL version, but

generate_series(timestamp, timestamp, interval)

was not available before 8.4

So maybe you are using an outdated version?
