Answering my own question, the distribution of the current logfile name could be done trough a file handle.
would you mind commenting on my suggestion so I can continue on that topic?
There is no portable way to redistribute a file handle.
Seems I didn't make clear enough what I mean.
I'd fopen a file handle in the postmaster, and all subsequent processes will inherit that handle just as they do for stderr; no redistribution required.
The log filename is written to that file when pg_logfile_rotate is called:
fseek(fh, 0, SEEK_SET);
fprintf(fh, "%s", newlogfilname);
fflush();
and all subprocesses may retrieve the filename when required by
char buf[MAXPGPATH]; fseek(fh, 0, SEEK_SET); fread(buf, 1, MAXPGPATH, fh); buf[MAXPGPATH-1]=0; // prevent buffer overflow logfile=fopen(buf, "a+");
