* glom/libglom/report_builder.cc: report_build_summary():
Remove any sort clause (ORDER BY) from the FoundSet because that makes
no sense for a single row with summary fields. It looks like recent versions
of PostgreSQL have become more strict about this, producing this error, for
instance:
column invoices.invoice_id must appear in the GROUP BY clause or be used in an aggregate function
* Makefile_tests.am:
* tests/test_selfhosting_new_then_report_summary.cc: Add a test for this.
This fixes bug #669281 (alien)
