Document array of fragments?

[perifer]

Is an array of fragments missing in the README?

sql`${[sql`select 1`, sql`as result`]}`

I first saw this in use in this example:

https://github.com/porsager/postgres/issues/217#issuecomment-1156958623

${ 
  Object.keys(rows[0]).map((x, i) =>
    sql`${ i ? sql`,` : sql``}${ sql(x) } = excluded.${ sql(x) }`
  )
}

For me it wasn't super obvious that you could do that, but it's useful! Maybe add it to https://github.com/porsager/postgres#quick-primer-on-interpolation, something like

Interpolation syntax	Usage	Example
${ sql`` }	for keywords or sql fragments	await sql`SELECT * FROM users ${sql`order by age desc` }`
${ sql(string) }	for identifiers	await sql`SELECT * FROM ${sql('table_name')`
${ sql([] or {}, ...) }	for helpers	await sql`INSERT INTO users ${sql({ name: 'Peter'})}`
${ 'somevalue' }	for values	await sql`SELECT * FROM users WHERE age = ${42}`
${ [sql``, sql``, ...] }	for sql fragments	some short but still useful example?

[perifer]

Or maybe add it to the first example?

Interpolation syntax	Usage	Example
${ sql`` or [sql``, ...] }	for keywords or sql fragments	await sql`SELECT * FROM users ${sql`order by age desc` }`
${ sql(string) }	for identifiers	await sql`SELECT * FROM ${sql('table_name')`
${ sql([] or {}, ...) }	for helpers	await sql`INSERT INTO users ${sql({ name: 'Peter'})}`
${ 'somevalue' }	for values	await sql`SELECT * FROM users WHERE age = ${42}`
