PostgresDialect

PostgreSQL dialect that uses the pg library.

The constructor takes an instance of PostgresDialectConfig.

import { Pool } from 'pg'

new PostgresDialect({
  pool: new Pool({
    database: 'some_db',
    host: 'localhost',
  })
})

If you want the pool to only be created once it's first used, pool can be a function:

import { Pool } from 'pg'

new PostgresDialect({
  pool: async () => new Pool({
    database: 'some_db',
    host: 'localhost',
  })
})

class PostgresDialect implements Dialect {

constructor(config: PostgresDialectConfig);

createAdapter(): DialectAdapter;

createDriver(): Driver;

createIntrospector(db: Kysely<any>): DatabaseIntrospector;

createQueryCompiler(): QueryCompiler;

}
