如何在 Windows 上只安装 PostgreSQL 的客户端工具？

我在 Linux 系统上有一个 PostgreSQL 数据库，我想从我的 Windows PC 上访问它。但是我能找到的唯一的 Windows 二进制文件是完整的安装程序，其中包括数据库服务器和客户端。

有没有可能从任何地方为 PostgreSQL 安装一个只有客户端的 Windows 二进制文件？

(澄清一下，我想要标准的 PostgreSQL 客户机 psql ——而不是 GUI 客户机或独立工具)。

Unfortunately there is no real client "only" installer.

What you can do, is to download the ZIP archive of the complete Postgres binaries:

http://www.enterprisedb.com/products-services-training/pgbindownload

and then remove the "server" part from it.

When you unzip it, you get the following directories:

bin
doc
include
lib
pgAdmin III
share
StackBuilder
symbols

You can remove the doc, include, pgAdmin III, StackBuilder and symbols directories. As far as I can tell (but I am not sure) the client also doesn't need the share or lib directories, but you would need to test that. So that leaves only the bin directory.

I think the share directory could be needed for localized error messages in psql but I'm not sure about that.

Inside the bin directory you can essentially remove all .exe files (except psql.exe of course). You can also remove all wx*.dll files, they are only needed for pgAdmin. The libxml2.dll and libxslt.dll are also only needed for the server.

If you do want some of the other client tools, you might want to keep

  • pg_dump.exe
  • pg_dumpall.exe
  • pg_restore.exe

One drawback of this approach is that this requires the Visual C++ Redistributable to be installed. But you can overcome that as well by simply putting the MSVCR120.DLL from some computer where it is installed into the bin directory.

So that leaves you with these files (from the bin directory) that are required for the psql client:

  • iconv.dll (libiconv-2.dll in newer Postgres versions)
  • libeay32.dll
  • libintl-8.dll
  • libpq.dll
  • msvcr120.dll
  • ssleay32.dll
  • zlib1.dll
  • psql.exe

Of course you can also take all that from an existing Postgres installation without the need to download the ZIP archive.

It is obviously not a real installer, but if you put the cleaned up directory into a ZIP file, you can distribute that and whoever needs it just unzips the archive. Personally I find unzip to be the best "installer" anyway (I also use that to install the Postgres server, the Windows installer just has too many quirks)

Actually there are client CLI tools in pgAdmin. All you need is just to install it on your Windows machine from https://www.postgresql.org/download/windows/.

Then you'll be able to find those tools in folder like C:\Program Files (x86)\pgAdmin III\1.22 or C:\Program Files (x86)\pgAdmin 4\v2\runtime, depends on the pgAdmin version you have installed.

I realize this is an older question, but when I used the Windows installer for the latest version of Postgres (10.4), it gave me the option to install just the command line tools. I just unchecked server and pgadmin in the installer's window when prompted to choose what I wanted to install.

Thanks to everyone who has posted on this thread.

For what it's worth, I got psql.exe from PostgreSQL 10.10 working under Windows 10 with just the following files from the zip archive:

libcrypto-1_1-x64.dll
libiconv-2.dll
libintl-8.dll
libpq.dll
libssl-1_1-x64.dll
psql.exe

When connecting to AWS Redshift, I got the following error:

psql: FATAL: invalid value for parameter "client_encoding": "WIN1252"

I resolved this by running

set PGCLIENTENCODING=UTF8

I found this solution at https://forums.aws.amazon.com/thread.jspa?messageID=600088

HTH.

As of 2020, when you click download the full installer from here , click next and next and you get the option to install only the command line - tools enter image description here. Remember to add the path to the bin folder in the PATH variable.

Below are the steps I followed to connect to Amazon Redshift with postgres12 psql on windows:

  1. download postgres 12.4 from below location: https://www.enterprisedb.com/downloads/postgres-postgresql-downloads

  2. run the installer which will take few minutes and prompt you for installations options

  3. select command line tools as shown in below screenshot and install that

  4. Above will install postgres12 command line in below folder C:\Program Files\PostgreSQL\12\bin. Make sure to add this to your PATH environment variable

  5. open cmd and run command set PGCLIENTENCODING=UTF8

  6. run psql to connect to redshift. Make sure to change below parameters highlighted in red for your cluster endpoint, userid, copy script file name and log script file name respectively psql -h redshift-cluster-1.abcdefgh.us-east-1.redshift.amazonaws.com -U demo_user -d dev -p 5439 -f d:\demo\redshift_script.sql -L d:\demo\log_redshift_script.log

  7. all commands in redshift_script.sql file would get executed in PSQL and logs will be stored in log_redshift_script.log file

If there's pgadmin v4 installed then just copy these libraries (from C:\Program Files\pgAdmin 4\v4\runtime\):

libcrypto-1_1-x64.dll
libpq.dll
libssl-1_1-x64.dll

These were enough for me to connect from a client Windows 10 x64 PC to a remote Postgres 13 server. Note, that libraries coming with the ZIP archive mentioned above are slightly different and have more dependencies.

I kind of cheat. I install sqlbackupandftp.com on a Windows server - which has a free version that can schedule a single database backup. In the binaries, pg_dump.exe is there - typically on the C: drive like C:\Program Files (x86)\SQLBackupAndFTP\dbms\PostgreSql

There is a third-party command-line tool available known as PGCLI - A command-line interface for Postgres with auto-completion and syntax highlighting.

Install:

pip install pgcli

Connect to POSTGRES Server from Command-line:

pgcli -h localhost -U xyz -d app_db

For official documentation, visit PGCLI
