Hi hackers, I am trying to extend PostgreSQL by adding UDT and UDF for a custom use case and I am using C language extensions to do that.
However, I have a requirement of reading a text file from one of the C functions. The compiled *.so files are placed in the "pg_config --pkglibdir" directory and tried copying my text files there but it didn't work. I found that, when these shared libs are loaded they are run from a different working directory. In this case, what is the best way to refer to my text files from the C code other than giving the absolute path which can change from system to system. Thank you. Supun
