guys, i was able to install pg gem following this guide: https://stackoverflow.com/questions/54330779/how-to-correctly-load-a-gem-extension-in-aws-lambda

with some changement it works for me like this:

# Dockerfile
FROM lambci/lambda:build-ruby2.5

RUN yum install -y postgresql-devel postgresql
RUN gem update bundler

ADD Gemfile /var/task/Gemfile
ADD Gemfile.lock /var/task/Gemfile.lock

RUN bundle install --path /var/task/vendor/bundle --clean

maybe i also ran RUN yum update -y if that changed anything, i donno

# build.sh
set -e

rm -rf lib && rm -rf vendor && mkdir lib && mkdir vendor

docker build -t lambda-ruby2.5-postgresql10x -f Dockerfile .

CONTAINER=$(docker run -d lambda-ruby2.5-postgresql10x false)

docker cp \
    $CONTAINER:/var/task/vendor/ \
    ./

docker cp \
    $CONTAINER:/usr/lib64/libpq.so.5.5 \
    lib/libpq.so.5

# docker cp \
#     $CONTAINER:/usr/lib64/mysql/. \
#     lib/

docker rm $CONTAINER

hope this helps
