                      3: Decomposition error message summary
                      4: .sh SYNOPSIS
                      5: Error numbers 4500 \- 4999.
                      6: .sh DESCRIPTION
                      7: These error messages are associated with the process
                      8: of decomposing a multi-variable query
                      9: into a sequence of one variable queries
                     10: which can be executed by OVQP.
                     11: .sh ERRORS
                     12: .lp +8 8
                     13: 4602   query involves too many relations to create
                     14: aggregate function intermediate result.
                     15: .s3
                     16: In the processing of aggregate functions it is usually
                     17: necessary to create an intermediate relation for
                     18: .it each
                     19: aggregate function.
                     20: However, no query may have more than ten variables.
                     21: Since aggregate functions implicitly increase the number of variables
                     22: in the query, you can exceed this limit.
                     23: You must either break the
                     24: interaction apart and process the aggregate functions separately or
                     25: you must recompile \*(II to support more variables per query.
                     26: .s3
                     27: .lp +8 8

                     32: 4612   Query too long for available buffer space (sqsiz)
                     33: .lp +8 8

                     35: .lp +8 8
                     36: 4614   Query too long for available buffer space (agbufsiz).
                     37: .s3
                     38: These will happen if the internal form of the interaction processed by decomp
                     39: is too long for the available buffer space.
                     40: You must either shorten your
                     41: interaction or recompile decomp.
                     42: The name in parenthesis gives the internal
                     43: name of which buffer was too small.

                     46: 4615   Aggregate function is too wide or has too many domains.

                     48: The internal form
                     49: of an aggregate function
