There were several queries in 2014 regarding the absence of plpython2.dll from the Enterprise DB Postgres distribution for Win32. I should have thought that this omission was simply an oversight, which would have been rectified by now. However, I find that plpython2.dll is still missing from the EDB distribution of Postgres 9.6.3.
I have raised this with EDB. I received an acknowledgment, but I have not heard anything more. That is not surprising, as I am a person of no importance. A suggestion from Postgres.org that the library should be included might carry more weight.
The point was made in 2014 that Postgres.org is not responsible for what EDB includes in its distributions. On the other hand, there is a link to the EDB site in the Postgres site, and that might be taken as an endorsement. If EDB are not willing to provide the library, at the least you might include a warning that the distribution is not complete.
I suppose I could try to build the library myself. Would I have to build the whole of Postgres, or is is feasible to build just the library that I am missing? If the latter, which source files would I need to include in the build?
