deparse altered "COMMENT ON COLUMN" statement, the string is escaped and a ' is removed

[divyenduz]

Original query (with fingerprint 7bbdf5f425075dd4):

COMMENT ON COLUMN public.posts.reply_to_post_number IS 'If this post is a reply to another, this column is the post_number of the post it''s replying to. [FKEY posts.topic_id, posts.post_number]'

Deparsed query (with fingerprint 0):

COMMENT ON COLUMN public.posts.reply_to_post_number IS E'If this post is a reply to another, this column is the post_number of the post it's replying to. [FKEY posts.topic_id, posts.post_number]';

• The deparsed query also fails parsing with Error: syntax error at or near "s" 🤔

To reproduce:

const fs = require('fs')
const { parse, deparse } = require('pgsql-parser');

async function main() {
    const stmts = parse(`
COMMENT ON COLUMN public.posts.reply_to_post_number IS 'If this post is a reply to another, this column is the post_number of the post it''s replying to. [FKEY posts.topic_id, posts.post_number]'
    `)
    const stmts2 = deparse(stmts[0])
    console.log(stmts2)
}

main()
