Retain trailing 's' for table in Postgraphile - postgraphile

Question

Is there a way to disable the 'remove-the-plural-s' feature in Postgraphile?
I have a table OS in my database and am using the very awesome Postgraphile library to create a GraphQL interface for free. Everything is great, but Postgraphile is truncating my table name, thinking it is plural. So I get allOs instead of allOses and createO, updateO, etc...
I tried:
Adding an underscore after the table name, and then it just retains the entire thing with an underscore.
Adding an underscore (O_S) and then the plural has capital-s allOS but the singular is O_
A smart comment specifying E'#name os' but it still drops the s
A smart comment specifying E'#name oss' which then pluralizes correctly allOsses (haha) and keeps both for the singular oss
PS in case you see this Benjie/other contributors, your documentation is incredible and the library will save me months of work.

This change is performed by PostGraphile's inflector; however it doesn't always get it right (e.g. in this case) but fortunately it's possible to override it with a small plugin.
In this case, it's probably best to add specific exceptions to the pluralize and singularize functions; you can do this using makeAddInflectorsPlugin from our inflection system. Be sure to pass true as the second argument so that the system knows you're deliberately overwriting the inflectors.
const { makeAddInflectorsPlugin } = require('graphile-utils');
module.exports = makeAddInflectorsPlugin(oldInflectors => ({
pluralize(str) {
if (str.match(/^os$/i)) {
return str + 'ses';
}
return oldInflectors.pluralize(str);
},
singularize(str) {
if (str.match(/^osses$/i) {
return str.substr(0, 2);
}
return oldInflectors.singularize(str);
}
}), true);
I'm glad you're enjoying PostGraphile 🤘
