Обсуждение: C function to return double precision[][]
Is there any piece of code I could see how to achieve $subject ? I haven’t found anything in the standard library or contrib modules. I’m trying to build ArrayType ** of sorts and return a Datum of those but I can’t seem to manage memory correctly.

There is an example in PL/R here: https://github.com/postgres-plr/plr/blob/20a1f133bcf2bc8f37ac23da191aea590d612619/pg_conversion.c#L1275 which points to here with number of dims == 2: https://github.com/postgres-plr/plr/blob/20a1f133bcf2bc8f37ac23da191aea590d612619/pg_conversion.c#L1493 This is all generic to the element type (i.e. not specifically float8), but the needed type conversion stuff happens in here: https://github.com/postgres-plr/plr/blob/20a1f133bcf2bc8f37ac23da191aea590d612619/plr.c#L1109 HTH, -- Joe Conway PostgreSQL Contributors Team RDS Open Source Databases Amazon Web Services: https://aws.amazon.com
