Description:
When starting standby server it tries to read WAL from primary server but
freezes on the same record.
Logs below are in russian so i'll translate.
invalid record length at 42/99074DF0: wanted 24, got 0 ...
The problem is that standby never starts. It will repeat this message every
"wal_retrieve_retry_interval" (10 seconds here) with no progress. After
enabling debug logs I got warning "mapped win32 error code 2 to 2". Which is
not informative how to fix the error.
