Bug reference:      3635
Logged by:          libpg.dll problem while changing from version 8.2.4
no-installer to 8.2.5 no-installer
Email address:      Pawo509(at)poczta(dot)onet(dot)pl

Description:        libpg.dll localization change
Details: 

I was using PostgreSQL in version
postgresql-8.2.4-1-binaries-no-installer.zip under Windows. I did the
following:
1. I unzipped PostgreSQL into D:\PostgreSQL and created directory named
"database" inside.
2. I exceuted (on non-administrator account "postgres"): initdb -D
"D:\PostgreSQL\database" -U root --encoding=UTF8 --no-locale
3. I executed (as an administrator): pg_ctl -D "D:\PostgreSQL\database"
register -N myPostgreSQLService
Everything worked ok. 
I changed version to postgresql-8.2.5-1-binaries-no-installer.zip, and tried
to repeat procedure above."initdb" failed because libpq.dll was not found. I
discovered that localization of this library changed from /bin to /lib
directory. When I added this /lib to PATH everything worked OK.
Does anyone know what is the reason of that change? According to version
numbering of PostgreSQL, changing minor version number (here: 4->5) means
small bug fixing and no enhancements. Changing library localization is
rather not a bug fix, and in my opinion there should be a comment about that
in release notes if someone wants to use no-installer version.
