add this path "C:\Program Files\PostgreSQL\11\bin"
to the path in environment variables.

I have found a solution for this.

download posgresql x32 binaries. then extract and enter the bin folder. take these 4 files:
- libcrypto-1_1.dll
- libiconv-2.dll
- libpq.dll
- libssl-1_1.dll

then copy the 4 files into the application folder

the full version consists of the following files

libcrypto-1_1.dll
libiconv-2.dll
libintl-8.dll
libpq.dll
libssl-1_1.dll
zlib1.dll

To avoid a lot of guessing:
I installed pgAdmin 4 (in my case the Windows 64-bit version) and checked which dll's this program uses (see C:\Program Files\pgAdmin 4\v4\runtime).
In my case only 4 (not including the Qt- and Python-stuff):
libcrypto-1_1-x64.dll
libpq.dll
libssl-1_1-x64.dll
zlib.dll

I copied these to my application directory and could connect without errors!
I assume the same can be done with the Windows 32-bit version.
