Please answer these questions before submitting your issue.

1. What did you do? If possible, provide a simple script for reproducing the error.

I installed "swoole/library": "^5.1" using command composer require swoole/library

Swoole Server was working fine previously. FYI. I had installed swoole using command below:

cd /tmp && \
git clone https://github.com/swoole/swoole-src && \
cd swoole-src && \
git checkout v5.1.2 && \
phpize8.3 clean && \
phpize8.3 && \
./configure --enable-openssl \
        --enable-mysqlnd \
        --enable-sockets \
        --enable-http2 \
        --enable-swoole-curl \
        --enable-swoole-json \
        --enable-swoole-pgsql \
        --with-postgres \
        --enable-debug \
        --enable-debug-log \
        --enable-trace-log \
        --enable-thread-context \
        --enable-cares \
        --with-php-config=/usr/bin/php-config8.3 && \
sudo make && sudo make install

2. What did you expect to see?

No PHP Fatal Error / Warning.

3. What did you see instead?

When i try to run Server from command line, i get following Warning and Error:

Swoole has built-in libraries, so there is no need to install them.

Modify php.ini and set swoole.enable_library to off

Actually, the purpose of installing swoole\library was to to create a PostgreSQL Object Pool by extending from Connection Pool class. I have just created that directly in my project folder (not in vendor). However, i will provide my implmentation as a proposal for your review (As a PR), shortly so that it can be merged into swoole\library. Thanks for your prompt answer. It removed the confusion.
