or the install instructions included in cygwin shell (which are not so
accurate)...
Funnily, plpgsql is not installed by default. Make sure you add it to
your databases, eg for template1, from the cygwin cmd-line:

Abstract:
This is the README for the Cygwin PostgreSQL distribution.
PostgreSQL is an advanced Object-Relational database management system
(DBMS) that supports almost all SQL constructs (including transactions,
subselects and user-defined types and functions).
The Cygwin PostgreSQL package is very monolithic compared its RPM
counterparts and its contents is roughly analogous to the aggregation
of the following PostgreSQL RPMs:
postgresql-devel
postgresql-docs
postgresql-jdbc
postgresql-libs
postgresql-perl
postgresql-python
postgresql-server
Requirements:
The following packages or later are required to build and/or execute
Cygwin PostgreSQL:
crypt 1.0-1
cygipc 1.11-1
readline 4.2a-1
libreadline5 4.2a-1
zlib 1.1.3-6
cygwin 1.3.10-1
Sun JDK 1.3
Ant 1.3
Install:
There are two types of Cygwin PostgreSQL installations -- basic and NT
services. The basic installation is good for casual use on any version of
Windows, but required on Windows 9x/Me. The NT services installation is
good for a more production environment, but is only available on Windows
NT/2000. Note that this installation type is very similar to the normal
Unix installation with just some Cygwin/Windows variations. You should
choose the type which best meets your needs and/or is constrained by your
platform.
Regardless of the installation type, the first step is to install the
latest cygipc from:
http://www.neuro.gatech.edu/users/cwilson/cygutils/cygipc/index.html
The following is the basic Cygwin PostgreSQL installation procedure:
1. Start the cygipc ipc-daemon:
$ ipc-daemon &
2. Initialize PostgreSQL:
$ initdb -D /usr/share/postgresql/data
3. Start the PostgreSQL postmaster:
$ postmaster -D /usr/share/postgresql/data &
4. Connect to PostgreSQL:
$ psql template1
The following is the NT services Cygwin PostgreSQL installation procedure:
1. Install the cygipc ipc-daemon as a NT service:
# ipc-daemon --install-as-service
2. Create the "postgres" user account:
# cmd /c lusrmgr.msc # [3]
# mkpasswd -l -u postgres >>/etc/passwd
3. Grant the "postgres" user the "Log on as a service" user right:
# cmd /c secpol.msc [4]
4. Install postmaster as a NT service (one line):
# cygrunsrv --install postmaster
--path /usr/bin/postmaster --args "-D /usr/share/postgresql/data -i"
--dep ipc-daemon --termsig INT --user postgres --shutdown # [5] [6]
5. Create the PostgreSQL data directory:
# mkdir /usr/share/postgresql/data
6. Change ownership of the PostgreSQL data directory:
# chown postgres /usr/share/postgresql/data
7. Initialize PostgreSQL (*when running under the "postgres" account*):
$ initdb -D /usr/share/postgresql/data
5. Start the cygipc ipc-daemon:
# net start ipc-daemon # [7]
6. Start postmaster:
# net start postmaster # [7]
7. Connect to PostgreSQL:
# psql -U postgres template1 [8] [9]
The following are the notes to the above:
[1] The "#" prompt indicates running as a user which is a member of the
Local Administrators group.
[2] The "$" prompt indicates running as the "postgres" user. Log in as
"postgres" or use ssh to emulate Unix's "su" command.
[3] On Windows 2000, this starts the "Local Users and Groups" applet.
On Windows NT 4.0, do the analogous operation.
[4] On Windows 2000, this starts the "Local Security Settings" applet.
On Windows NT 4.0, do the analogous operation.
[5] Do not use rxvt for this step because the password exchange will not
work properly.
[6] Clean postmaster shutdown will only work with a post Cygwin 1.3.2
snapshot from 2001-Jul-28 or later.
[7] Cygwin's bin directory (e.g., C:Cygwinbin) must be added to the
Windows NT/2000's system PATH and the machine rebooted for the SCM
to find cygwin1.dll.
[8] Actually, psql can run under any user account.
[9] One can use PostgreSQL's createuser command or set PGUSER to obviate
the need to specify "-U postgres" on the psql command line.
Source:
As configured, the PostgreSQL source builds OOTB under Cygwin with
only one minor Perl related caveat. So, the source has been patched to
correct this issue. I have submitted the following patch:
http://archives.postgresql.org/pgsql-patches/2002-02/msg00029.php
for consideration and it has been accepted into PostgreSQL CVS.
Additionally, the source has been patched so that InstallXLogFileSegment()
uses rename() instead of link()/unlink() to avoid a Windows open file
permission denied problem. I have submitted the following patch:
http://archives.postgresql.org/pgsql-patches/2002-05/msg00029.php
for consideration and it has been accepted into PostgreSQL CVS.
I also added the following files to the source archive:
CYGWIN-PATCHES/README
CYGWIN-PATCHES/build.sh
CYGWIN-PATCHES/postgresql.patch
and renamed the original source archive to match Cygwin's setup.exe
naming conventions.
To restore the PostgreSQL source to its original state, perform the
following:
$ cd postgresql-$version-$package
$ patch -R -p1 <CYGWIN-PATCHES/postgresql.patch
$ rm -fr CYGWIN-PATCHES
where $version is the PostgreSQL version (e.g., 7.2) and $package is the
Cygwin package number.
Build:
This distribution has been configured as follows (one line):
configure --enable-multibyte --with-python --with-perl --with-java
--with-CXX --prefix=/usr --sysconfdir=/etc --docdir=/usr/doc/postgresql-$version
where $version is the PostgreSQL version (e.g., 7.2).
See CYGWIN-PATCHES/build.sh in the source archive for my exact build
recipe for configuring, making, and packaging this distribution.
Test:
On 9X/ME, it has been reported that Cygwin PostgreSQL hangs at random
places during the regression test. Unfortunately, at the time of this
writing, no one has tracked down the root cause of these hangs.
Issues:
1. make check can generate spurious regression test failures due to overflowing
the the listen() backlog queue which generates connection refused errors. Note
that make installcheck does not have this problem since it runs all tests
sequentially instead of in large concurrent groups.
2. It is recommended to delete all cygipc temporary files (/tmp/cygipc* and
/tmp/MultiFile*) before starting postmaster under a different user account.
Otherwise, postmaster will fail to start due to IPC errors.
