I am using Postgrsql 9.0 and writing a C-language extension. The extension takes an n-dimension array and performs a lookup on that array. Right now I’m stuck on determining the dimensions of the array data passed in. No matter what I pass in as the array parameter (the first parameter) I’m getting a ARR_NDIM of 2.
For example, I get an ARRY_DIM of 2 for each of these queries:
SELECT getone(ARRAY[[10.1,11.2,12.3],[20.1,21.2,22.3]], POINT(1.0,1.0), 1.5, 1.0, 1.0);
SELECT getone(ARRAY[[10.1,11.2,12.3],[20.1,21.2,22.3],[31.1,33.2,35.3],[44.1,45.2,46.3]], POINT(1.0,1.0), 1.5, 1.0, 1.0);
To my way of thinking about these arrays, I should be getting the ARR_NDIM answer of 2 for the first query and an ARR_NDIM answer of 4 for the second one.
Is this a bug or am I missing something?
