Aggregation support absent on postgres < 8.2

Description

Running the test suite on a clean check out of r10628, with PostgreSQL 8.1 and psycopg2, I get numerous errors from the regressiontests/aggregation_regress/, including:

    ProgrammingError: function stddev_pop(integer) does not exist
    ProgrammingError: function stddev_samp(integer) does not exist
    ProgrammingError: function var_pop(integer) does not exist
    ProgrammingError: function var_samp(integer) does not exist

I believe that these aggregates were first implemented in PostgreSQL 8.2, so either the aggregation code itself or at least the test cases should be conditional on that version.

See [10142] for an existing error message on PostgreSQL 8.2 to 8.2.4, which could perhaps be extended downwards?

Has patch: set

(I meant to refer to #10142 and #10289, not [10142])

This definitely needs to be done, but I'm going to wait until resolution on #10842 before committing, as this will make version comparisons much more robust.

Resolution: → fixed
Status: new → closed

(In [10731]) Fixed #10906 -- Added a check for PostgreSQL pre 8.2 when using StdDev/Variance aggregates. Thanks to Richard Davies for the report and patch.
