Increase size of bgw_library_name.
This commit increases the size of the bgw_library_name member ofthe BackgroundWorker struct from BGW_MAXLEN (96) bytes to MAXPGPATH(default of 1024) bytes so that it can store longer file names(e.g., absolute paths).Author: Yurii RashkovskiiReviewed-by: Daniel Gustafsson, Aleksander AlekseevDiscussion:https://postgr.es/m/CA%2BRLCQyjFV5Y8tG5QgUb6gjteL4S3p%2B1gcyqWTqigyM93WZ9Pg%40mail.gmail.com
