Attached is a patch adding support for the gamma and log-gamma
functions. See, for example:
https://en.wikipedia.org/wiki/Gamma_function
I think these are very useful general-purpose mathematical functions.
They're part of C99, and they're commonly included in other
mathematical libraries, such as the python math module, so I think
it's useful to make them available from SQL.
The error-handling for these functions seems to be a little trickier
than most, so that might need further discussion.

Hi! The patch file seems broken.
git apply gamma-and-lgamma.patch
error: git apply: bad git-diff — exptec /dev/null in line 2
