Bug reference:      16273
Logged by:          sun qiankun

PostgreSQL version: 12.1
Operating system:   centos7
Description:

when i read the code  in src/bin/initdb/initdb.c.
At the function: set_info_version, we use pg_strdup to malloc  memory, but
we don't free it.

Detail info:
char       *vstr = pg_strdup(PG_VERSION);

we can fix it at the end of the function use free(vstr).

There are lots of minor memory leaks in initdb.  We don't really care
that much, because the program executes over a fixed set of data and
then terminates.
