Meta attribute macro for Crosstab pivots

[jbrestel]

Add macro whichis populated by running of an attribute meta query. This allows us to specify columns returned by a "pivot" (crosstab function in postgres).

NOTE: The crosstab function is postgres specific. No attempt was made to name things generically.

Tested on my ToxoDB dev site for phenotype and RNASeq (see related PRs)

Hmm.. Actually something may not be write with the colTypes. The query being run looks like this:

SELECT ta.source_id, ta.project_id, ta.gene_source_id, p.*
FROM apidbtuning.TranscriptAttributes ta
LEFT OUTER JOIN (
SELECT * FROM public.crosstab(
'SELECT genes.string_value as gene_id, av.attribute_stable_id, av.number_value
FROM eda.attributevalue_sdfae3769c3_gnPhntyD av,
(SELECT gnPhntyD_stable_id, string_value
FROM eda.attributevalue_sdfae3769c3_gnPhntyD
WHERE attribute_stable_id = ''VEUPATHDB_GENE_ID'') genes
WHERE av.gnPhntyD_stable_id = genes.gnPhntyD_stable_id
AND av.attribute_stable_id != ''VEUPATHDB_GENE_ID''
ORDER BY 1, 2',
'SELECT stable_id
FROM eda.attributegraph_sdfae3769c3_gnPhntyD
WHERE has_values = 1
AND stable_id != ''VEUPATHDB_GENE_ID''
AND data_type = ''number''
AND (hidden IS NULL OR NOT (hidden::jsonb @> ''["variableTree"]''::jsonb))
ORDER BY stable_id'
) AS ct(gene_id text, VAR_0699dcd5 text, VAR_32e9589b text, VAR_41fe31ad text, VAR_45083826 text, VAR_4b1f735e text, VAR_69d23b9f text, VAR_8e5c07ee text, VAR_90b02f16 text, VAR_92eac45c text, VAR_c067524e text, VAR_c10f5a2e text, VAR_c33fe1b0 text, VAR_c494aa69 text, VAR_ccdd8654 text, VAR_d016448c text, VAR_d23519d9 text, VAR_e06c02ce text, VAR_e2db12e5 text, VAR_f3418d2f text)
) p ON ta.gene_source_id = p.gene_id

The column being returned "av.number_value" is numeric but the WDK is casting them all to "text" when populating the macro.

NOTE: Somehow it seems to be getting this right on the front end because i can see histograms and the sorting by numeric seems to be working. Not sure what is going on there.

Ok. the text vs. numeric issue has been resolved. It is behaving correctly now
