How to Perform Efficient Bulk Inserts in PostgreSQL with pgx and Go?

Bulk INSERT in PostgreSQL Using Go and pgx

This code snippet demonstrates the correct way to perform bulk insertion in PostgreSQL using the pgx library in Go.

Issue Description

The original code attempted to manually construct an SQL statement for bulk insertion, but encountered an error due to incorrect argument count.

Solution with pgx.CopyFrom

Instead of manually crafting the SQL statement, we leverage the pgx.Conn.CopyFrom method, which utilizes PostgreSQL's copy protocol for efficient bulk insertion:

<code class="go">rows := [][]interface{}{
    {&quot;abc&quot;, 10},
    {&quot;dns&quot;, 11},
    {&quot;qwe&quot;, 12},
    {&quot;dss&quot;, 13},
    {&quot;xcmk&quot;, 14},
}

copyCount, err := conn.CopyFrom(
    pgx.Identifier{&quot;keys&quot;},
    []string{&quot;keyval&quot;, &quot;lastval&quot;},
    pgx.CopyFromRows(rows),
)
if err != nil {
    fmt.Fprint(os.Stderr, &quot;Error : \n&quot;, err)
}</code>

This code effectively inserts the test keys into the keys table in a single operation, optimized for bulk insertion performance.
