I appreciate (and agree with) the concern about the fragility of the
codebase. The maintainer knows that anything except adding ORDER BY
is a kludge.
Now, the aforementioned notwithstanding...
Aside from disabling enable_hashagg (which, according to the
documentation, is performance-expensive), what other options do I
have?
What are the ramifications of renaming the table (containing 8000
rows) and creating a view of the same name?
Assuming it's possible, would the efficiency of a rule to rewrite the
query be an acceptable alternative?
Thanks in advance for any insight and suggestions!
