Thank you,

Just for the information, cfbot complains about this patch because:

pgstatfuncs.c: In function ‘pgstat_get_syscache_stats’:
pgstatfuncs.c:1973:8: error: ignoring return value of ‘fread’,
declared with attribute warn_unused_result [-Werror=unused-result]
   fread(&cacheid, sizeof(int), 1, fpin);
        ^
pgstatfuncs.c:1974:8: error: ignoring return value of ‘fread’,
declared with attribute warn_unused_result [-Werror=unused-result]
   fread(&last_update, sizeof(TimestampTz), 1, fpin);
        ^

I'm moving it to the next CF as "Waiting on author", since as far as I
understood you want to address more commentaries from the reviewer.
