preferred package for debugging query text?

Hi, I’m wondering if there is a preferred package, extension, or method for providing more detail when you get a syntax error back from the parser (for instance, one that listed line number, column of the error)

for instance, right now:

error: syntax error at or near "as"
    at Parser.parseErrorMessage (/home/collspec/projects/staff-portal/sprint-server/node_modules/pg-protocol/dist/parser.js:278:15)

desired behavior:

error: syntax error at or near "as", line 5, column 7
    at Parser.parseErrorMessage (/home/collspec/projects/staff-portal/sprint-server/node_modules/pg-protocol/dist/parser.js:278:15)

    at Socket.emit (events.js:400:28)
    at addChunk (internal/streams/readable.js:293:12)
    at readableAddChunk (internal/streams/readable.js:267:9)
    at Socket.Readable.push (internal/streams/readable.js:206:10)
    at TCP.onStreamRead (internal/stream_base_commons.js:188:23) {
  length: 91,
  severity: 'ERROR',
  code: '42601',
  detail: undefined,
  hint: undefined,
  position: '157',
  internalPosition: undefined,
  internalQuery: undefined,
  where: undefined,
  schema: undefined,
  table: undefined,
  column: undefined,
  dataType: undefined,
  constraint: undefined,
  file: 'scan.l',
  line: '1180',
  routine: 'scanner_yyerror'
}

Parsing errors returned from the PG package are almost useless since there is no info about file location where broken query is.

mysql2 package on the other hand do returns file location with broken query

For information, since version 8.4.0, you can import DatabaseError interface (see https://github.com/brianc/node-postgres/blob/54b87523e29ea53379d7b9a26e45f83886f371af/CHANGELOG.md#pg840)

the DatabaseError has the following fields : https://github.com/brianc/node-postgres/blob/6121bd3bb0e0e8ef8ec8ad5d02f59fef86b2f992/packages/pg-protocol/src/messages.ts#L97 unit tests are there : https://github.com/brianc/node-postgres/blob/4b229275cfe41ca17b7d69bd39f91ada0068a5d0/packages/pg/test/integration/client/query-error-handling-tests.js#L81

offical docs about error properties : https://www.postgresql.org/docs/13/protocol-error-fields.html

official error codes : https://www.postgresql.org/docs/current/errcodes-appendix.html

Somebody has already converted these on js constants here : https://github.com/LinusU/pg-error-constants
but see LinusU/pg-error-constants#1
