Package Exports
- pg-tsquery
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (pg-tsquery) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Text-Search parser for PostgreSQL
Why?
Using pg's to_tsquery directly with user input can throw errors. plainto_tsquery sanitizes the user input, but it's very limited (it just puts an and between words), similarly websearch_to_tsquery does this, except between quotes.
This module allows customizable text-search operators (and, or, followedBy, not, prefix, parentheses, quoted text), while also preserving quoted text just like websearch_to_tsquery.
