| Installing PostgreSQL on Windows Using Cygwin FAQ
 | |
| =================================================
 | |
| 
 | |
| $Date: 2007/10/09 01:28:24 $
 | |
| 
 | |
| PostgreSQL requires the appropriate subset of Cygwin DLLs to be
 | |
| installed in order that it functions under Windows.
 | |
| 
 | |
| This document assumes that you do not have Cygwin already installed
 | |
| on your system.  If that is not the case, then you will need to
 | |
| adjust these instructions accordingly.
 | |
| 
 | |
| 1.  Download and run the Cygwin installer.  Visit http://cygwin.com/ and
 | |
|     click on the "Install Cygwin now' link.  This will prompt you
 | |
|     to download a "setup.exe".  Save this file somewhere on your
 | |
|     system and then execute it.
 | |
| 
 | |
| 2.  Proceed through the Cygwin install wizard.  Choose 'Install from
 | |
|     Internet', specify a Local Package Directory and choose a mirror
 | |
|     site that's close to you.  Answer the other installer questions
 | |
|     appropriately for your configuration.
 | |
| 
 | |
|     When you come to the point of choosing which packages to install,
 | |
|     expand the 'Database' section and click 'Skip' next to PostgreSQL
 | |
|     to change it to the latest version of PostgreSQL available for
 | |
|     Cygwin.
 | |
| 
 | |
| 3.  Once the download and install process is complete, open a Cygwin
 | |
|     shell and do the following for a basic installation:
 | |
| 
 | |
|     3a.  Start cygserver for shared memory support.  To do this,
 | |
|          enter the command "/usr/sbin/cygserver &".  This program
 | |
|          needs to be running anytime you start the Postgres server
 | |
|          or initialize a database (initdb).
 | |
| 
 | |
|     3b.  Use the initdb command to create a new database cluster.  An
 | |
|          example command would be:
 | |
| 
 | |
|             initdb -D /usr/local/pgsql/data -W -E LATIN1
 | |
| 
 | |
|          Which will create a cluster in the /usr/local/pgsql/data
 | |
|          directory, will prompt for a superuser password and will
 | |
|          set the default database encoding to LATIN1.
 | |
| 
 | |
|     3c.  Start up the Postgres server.  Use a command similar to the
 | |
|          following:
 | |
| 
 | |
|             postgres -D /usr/local/pgsql/data
 | |
| 
 | |
|          This will start the server, and if successful you will
 | |
|          see some initial log entries, and an entry "LOG: database
 | |
|          system is ready".
 | |
| 
 | |
| 4.  You are now running a PostgreSQL server on your Windows machine.
 | |
| 
 | |
| 5.  It is possible to install cygserver and the Postgres server as
 | |
|     Windows NT services.  For information on how to do this, please
 | |
|     refer to the README document included with Cygwin PostgreSQL.  It
 | |
|     is installed in the /usr/share/doc/Cygwin directory.
 | |
| 
 | |
| Building from source
 | |
| --------------------
 | |
| 
 | |
| There are some points that are only relevant if you are building Cygwin
 | |
| PostgreSQL from source:
 | |
| 
 | |
| 1.  Set your path to use the Cygwin bin directory before the Windows
 | |
|     utilities.  This will help prevent problems with compilation.
 | |
| 
 | |
| 2.  Proceed according to the INSTALL file (i.e., ./configure; make; etc.)
 | |
|     noting the following Cygwin specific differences:
 | |
| 
 | |
|         o The GNU make command is called "make" not "gmake".
 | |
|         o The adduser command is not supported -- use the appropriate
 | |
|           user management application on Windows NT, 2000, or XP.
 | |
|           Otherwise, skip this step.
 | |
|         o The su command is not supported -- use ssh to simulate su
 | |
|           on Windows NT, 2000, or XP. Otherwise, skip this step.
 | |
| 
 | |
|     Alternatively, proceed according to the README file supplied with
 | |
|     the Cygwin PostgreSQL package.
 | |
| 
 | |
| Known issues
 | |
| ------------
 | |
| 
 | |
| 1.  Cygwin's AF_UNIX sockets are really implemented as AF_INET sockets
 | |
|     so they are inherently insecure.
 | |
| 
 | |
| 2.  "make check" can generate spurious regression test failures due to
 | |
|     overflowing the listen() backlog queue which causes connection
 | |
|     refused errors or hangs. You can limit the number of connections
 | |
|     using the MAX_CONNECTIONS option thus:
 | |
| 
 | |
|        make MAX_CONNECTIONS=5 check
 | |
| 
 | |
|     (On some systems you can have up to about 10 simultaneous connections).
 | |
| 
 | |
| 3.  The default cygserver configuration may need to be changed (e.g.,
 | |
|     increase SEMMNS) to prevent PostgreSQL from failing due to a lack of
 | |
|     system resources.
 | |
|

| Problem reports can be sent to pgsql-cygwin@postgresql.org.
