Installation Guide

Import the cgo.dump File

Step1. Install Docker

If Docker is not already installed, follow these steps:

  1. Linux/MacOS:
  2. Windows:

After installation, verify Docker is running with the following command:

docker --version

Step2. Install PostgreSQL 13 Using Docker

  1. Pull the PostgreSQL 13 image:

    docker pull postgres:13

  2. Create and run a PostgreSQL container:

    docker run -d \
  --name postgres13 \
  -e POSTGRES_USER=your_username \
  -e POSTGRES_PASSWORD=your_password \
  -e POSTGRES_DB=your_database \
  -p 5432:5432 \
  postgres:13
    • POSTGRES_USER: Set the PostgreSQL username (e.g., postgres).
    • POSTGRES_PASSWORD: Set the PostgreSQL password.
    • POSTGRES_DB: Set the default database name.
    • -p 5432:5432: Map port 5432 on your machine to port 5432 in the container.

  3. Check the container status:

    docker ps

    If successful, you will see a container named postgres13.

  4. Access the PostgreSQL container:

    docker exec -it postgres13 bash

Step3. Copy the cgo.dump File into the Container

Run the following command on your host machine to copy cgo.dump into the container:

docker cp cgo.dump postgres13:/tmp/cgo.dump

Step4. Import the cgo.dump File

  1. Access the container and switch to the PostgreSQL user:

    docker exec -it postgres13 bash
su - postgres

  2. Restore the database using pg_restore:

    pg_restore -U your_username -d your_database /tmp/cgo.dump
    • your_username: Specify the database username.
    • your_database: Specify the target database name.

  3. To clean the target database before importing, add the --clean option:

    pg_restore -U your_username -d your_database --clean /tmp/cgo.dump

  4. Verify the import: Log into the database and check the data:

    psql -U your_username -d your_database
\dt

Step5(Optional). Access the Imported Data using GUI

You can install PgAdmin to access the imported data using a graphical interface. You can download the installer from the official website

Build our Modified Go Toolchain based on Go1.17.7

Step1. Download Go1.7.7 toolchain source code

  1. download Go1.17.7 toolchain source code: https://go.dev/dl/go1.17.7.src.tar.gz
wget https://go.dev/dl/go1.17.7.src.tar.gz
  1. extract toolchain source code
tar -xzvf go1.17.7.src.tar.gz

Step2. Use our go1.17.7_cgoptr.tar.gz

  1. extract our go1.17.7_cgoptr.tar.gz
tar -xzvf go1.17.7_cgoptr.tar.gz
  1. overwrite the original Go1.17.7 toolchain source with the extracted file
cd go1.17.7_cgoptr
cp -r * ../go/
  1. build the modifiled toochain
cd ../go/src
./make.bash # build

note: to build the modified toolchain, your machine must have Go installation (need the Go compiler to build the Go toolchain). ref Download and install - The Go Programming Language for details.

  1. verify your build
cd ../bin
./go --version

you can add this to your $PATH. and modify your $GOROOT if you want to use the modified toolchain later.

see Go Wiki: InstallTroubleshooting - The Go Programming Language for how to set $GOROOT.
