I just want to make sure you didn't miss my post
in november, about this same subject:

If you read it and didn't have anything to suggest
it's fine for me and sorry for this remainder.

In my last trial, I saw cygserver at 100%

Looking at the log, the loops are:

return from WaitForMultipleObjects() ...

So pgAdmin II is no better, may be just a little

This function was designed at a time when the

lib/tclX.Y, so there is two times a lib + 4
pointer to extract the tclX.Y part.
But the value has changed to share/tclX.Y in
TclpInitLibraryPath(), and now lib + 4 points to
/tclX.Y, which is of no use !
Postgresql's configure --with-tcl uses
/lib/tclConfig.sh to know how to link with TCL. But in
package tcltk version 20030901-1, usr/lib/tclConfig.sh
contains:
TCL_LIB_SPEC=''
so something required by Postgres isn't found.
Please change to:
TCL_LIB_SPEC='-L/usr/lib -ltcl84'
