PG9.1 Static build over Windows

Howdy,

I want to link Postgresql client to my Qt project but I noticed that
C:/PostgreSQL/9.1/lib/libpq.lib points to dynamic libaray (libpq.dll) which
is not suiatble for static linking.

How can I link statically my application with Postgresql client?

P.S.
I'm using mingw48_32 not msvs; usually mingw48_32 uses *.a files for static
linking not *.lib
Build log of my project is:
----
mingw32-make[1]: Leaving directory
'F:/build-TestSSLConnection-Satic_postgresql-Release'
mingw32-make[1]: *** No rule to make target 'C:/PostgreSQL/9.1/lib/pq.lib',
needed by 'release\TestSSLConnection.exe'. Stop.
makefile:34: recipe for target 'release' failed
mingw32-make: *** [release] Error 2
17:12:37: The process "C:\Qt\Qt5.1.1\Tools\mingw48_32\bin\mingw32-make.exe"
exited with code 2.
Error while building/deploying project TestSSLConnection (kit:
Satic-postgresql)
When executing step 'Make'

Thanks in advance for help.
