Bug reference:      15856
Logged by:          Luc
Email address:      (redacted)
PostgreSQL version: 11.3
Operating system:   Microsoft Windows [Version 10.0.17763.557]

Cluster initialization via initdb fails on 11.3 while on previous versions
(tested 10.8 and 9.6.13) works OK with exactly the same command line.

Testing procedure (exactly the same for each version):
  1. Download binary files using official download link:
  2. Unpack to a local directory
  3. Run the console command: initdb.exe -D c:\test\db -E UTF8

Expected result: database cluster properly initialized on 11.3, 10.8 and
Actual result: database cluster initialization fails on 11.3 but works on
10.8 and 9.6.13 (see console outputs below).

Binaries used:
* 11.3 ->
* 10.8 ->
* 9.6.13 ->

Console output on 11.3

c:\test\pg11> bin\initdb.exe -D c:\test\db -E UTF8
The program "postgres" was found by "c:/test/pg11/bin/initdb.exe"
but was not the same version as initdb.
Check your installation.

c:\test\pg11> bin\initdb.exe -V
initdb (PostgreSQL) 11.3

c:\test\pg11> bin\postgres.exe -V
postgres (PostgreSQL) 11.3

Console output on 10.8 (similar on 9.6.13)

c:\test\pg10> bin\initdb.exe -D c:\test\db -E UTF8
The files belonging to this database system will be owned by user "Luc".
This user must also own the server process.

The database cluster will be initialized with locale
The default text search configuration will be set to "english".

WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.

Success. You can now start the database server using:

    bin/pg_ctl -D ^"c^:^\test^\db^" -l logfile start
