postgresql/snake-case-table-name

Why this matters

Quoted mixed-case identifiers (`"UserAccounts"`) preserve their case and force every caller to quote them — a steady source of `relation does not exist` errors. Unquoted `CamelCase` is silently lowercased by PostgreSQL and passes the rule.

Examples

CREATE TABLE "UserAccounts" (id INT PRIMARY KEY);

CREATE TABLE user_accounts (id INT PRIMARY KEY);

CREATE TABLE UserAccounts (id INT PRIMARY KEY); -- folded to useraccounts

Configure it

// eslint.config.js
import postgresql from "eslint-plugin-postgresql";

export default [
  {
    files: ["**/*.sql"],
    languageOptions: {
      parser: postgresql.configs.recommended.languageOptions.parser,
    },
    plugins: { postgresql },
    rules: {
      "postgresql/snake-case-table-name": [
        "warn",
        {
          allow: [],
        },
      ],
    },
  },
];

Options

allow string[] default: []

Identifiers to exempt from the rule. Useful for tables that must keep an external name (e.g. `KEYWORDS`, vendor schemas).
