The above error message and the following:
$ fgrep 126 /usr/include/w32api/winerror.h
#define ERROR_MOD_NOT_FOUND 126L
...
imply that plpython.dll is failing to load. I believe that this is
because a dependent DLL can not be found:
$ cygcheck plpython.dll
Found: .\plpython.dll
.\plpython.dll
C:\cygwin\bin\postgres.exe
C:\cygwin\bin\cygwin1.dll
C:\WINNT\System32\KERNEL32.dll
C:\WINNT\System32\ntdll.dll
*> C:\cygwin\bin\libpython2.2.dll
*> C:\cygwin\bin\cygcrypto.dll
*> C:\cygwin\bin\cygssl.dll
Do you have the above marked DLLs on you system? Does python work
properly from bash?
BTW, the following seem to work OK for me:
$ psql
Welcome to psql 7.3b3, the PostgreSQL interactive terminal.
