The following bug has been logged on the website: Bug reference: 16217 Logged by: Matthias Apitz Email address: (redacted) PostgreSQL version: 11.4 Operating system: SuSE Linux SLES 12 SP4 Description: Actually, the ecpg pre-compiler resolves ESQL/C statements like EXEC SQL SELECT .... into a function call to the executer in the ecpglib as: ECPGdo(__LINE__, ...); where __LINE__ is later substituted by the C-precompiler by the current line number as an integer. The purpose is mostly for logging features like:  [14.01.2020 12:05:18:433]: ECPGtrans on line 1108: action "rollback"; connection "sisis71" i.e. to have the line number in the log statement (btw: the date and timestamp is already a local modification we did to bring the log line in sync with other logs our application is writing). In a real world server application written in some hundreds foo.pgc files (a generated application interface with the pgc files based on the 400 tables in the database), it would be nice to have the call done like this: ECPGdo(__LINE__, __FILE__, ...) and the resulting log line like this:  [14.01.2020 12:05:18:433]: ECPGtrans on line 1108 in file D01buch.c: action "rollback"; connection "sisis71" As this is an additional parameter to ECPGdo() function and would invalidate existing/compiled applications it should be somehow implemented optional, adding a new option to the precompiler command ecpg, generating calls to a changed function as ECPGdoNew(....) which stores the __FILE__ arg in some static variable, calling the old function ECPGdo() without the __FILE__ arg and the logging routines below use the static variable if set. Or something like this. Before hacking this into the ecpglib code by my own, I wanted to file this here as an oficial Change Request.
