+
+`@pgsql/enums` is a TypeScript library providing enum definitions for PostgreSQL AST nodes, primarily used in conjunction with [`pgsql-parser`](https://github.com/constructive-io/pgsql-parser). It offers a comprehensive and type-safe way to work with PostgreSQL enum values in query parsing and AST manipulation.
+
+
+## Installation
+
+Install the package via npm:
+
+```bash
+npm install @pgsql/enums
+```
+
+## Usage
+
+Here's a simple example showing how to work with enums, converting between enum names and their numeric values:
+
+```ts
+import { ObjectType } from '@pgsql/enums';
+
+// Get the numeric value of an enum
+const tableValue = ObjectType.OBJECT_TABLE;
+console.log(tableValue); // 41
+
+// Convert from value back to enum name
+const enumName = ObjectType[41];
+console.log(enumName); // "OBJECT_TABLE"
+
+// Use in comparisons
+if (someNode.objectType === ObjectType.OBJECT_TABLE) {
+  console.log("This is a table object");
+}
+```
+
+## Versions
+
+Our latest is built with PostgreSQL 17 enum definitions.
