Description: does not work -z option of pg_basebackup
Details:
it seems that the -z option of pg_basebackup does not work correctly.
In getopt_long() function, there is not 'z' in 3rd argument.
And Z_DEFAULT_COMPRESSION are defined as (-1) in my zlib.h and it does only
test (compresslevel > 0) in the code, so the command does not compress
anyway.
$ diff pg_basebackup.c.DIST pg_basebackup.c
