Fixes #30953

Summary

@prisma/adapter-pg parsed money values by dropping the first character (money.slice(1)). Postgres formats money using lc_monetary, so values that aren't cast to numeric, like _sum results and $queryRaw columns, can come back as $1,234.50 or -$120.00. Those became 1,234.50 and $120.00, and Decimal.js threw Invalid argument. The parser now keeps only the sign, the digits and the decimal point. Like before, it assumes a . decimal point.

Testing performed

• Added customParsers tests in packages/adapter-pg/src/__tests__/conversion.test.ts for $999.50, $1,234.50, -$120.00, -$1,620.00, $0.00 and a money array. Without the fix, 4 of them fail. With it, all pass.
• pnpm exec vitest run in packages/adapter-pg on the v7 branch (Node 22, Docker): all 3 test files pass.
• prettier --check passes. eslint reports no errors on the changed files (only warnings that were already there).
• I didn't run the integration tests against a live Postgres.

Walkthrough

The PostgreSQL adapter now removes non-numeric formatting characters from money values. Tests cover parsing currency-formatted scalar values and arrays, including values with thousands separators and negative signs.

The fix handles common en_US-style money values such as $1,234.50 and -$120.00. With some PostgreSQL monetary locales, however, it can now return wrong amounts silently instead of throwing. Parenthesized negatives become positive, and decimal-comma values are inflated by a factor of 100. Consider handling these formats or rejecting unsupported ones before merging, unless the supported locale scope is explicitly limited to . as the decimal point.

Full details: Title check

Explanation

The title names the adapter, the money parsing fix, and the two input shapes it covers (separators and a minus sign). The changeset matches this. The conversion.ts change makes normalize_money keep only digits, minus signs, and decimal points. The new customParsers tests cover thousands separators and negative values. The title is specific and describes the main change.

Explanation

Issue #30953 (direct) requires that @db.Money values parse without DecimalError in aggregate _sum, groupBy _sum, and $queryRaw results, including negative values and values with thousands separators. The reproduced failures come from normalize_money in packages/adapter-pg/src/conversion.ts, which used money.slice(1). The head replaces it with money.replace(/[^\d.-]/g, ''). This keeps the sign, digits, and '.' only. Traced inputs: '$1,234.50' gives '1234.50', '-$120.00' gives '-120.00', '$999.50' gives '999.50'. The MONEY scalar parser and the MONEY_ARRAY parser (791, via normalize_array) both use this function, so _sum and $queryRaw money columns reach the fixed path. The added tests in conversion.test.ts cover these inputs, a zero value, and a quoted money array. The issue lists stripping non-digit characters as an acceptable parser-level approach. Limitations: (1) The fix assumes '.' as decimal separator, as the PR states. A locale with ',' as decimal separator would parse silently to a wrong value, not throw. The issue reproduction uses en_US.UTF-8, so this does not break the stated requirement. (2) The PR does not change the compiler to cast SUM to ::numeric. The issue presents that as an option, not a requirement. (3) Integration tests against live Postgres were not run. The end-to-end path is confirmed by code inspection only.

Full details: Out of Scope Changes check

Explanation

The whole-PR diff against the merge base changes two files. packages/adapter-pg/src/conversion.ts changes only normalize_money, the parser named in issue #30953. packages/adapter-pg/src/tests/conversion.test.ts adds a customParsers test suite for MONEY and MONEY_ARRAY and imports pg and customParsers for those tests. The existing mapArg tests are unchanged. Every change connects directly to the money parsing objective. No unrelated changes were found. The title checklist item in the PR description is administrative and is not a code change.

Preserve parenthesized negative amounts.

With glibc en_SG, PostgreSQL formats negative money as ($120.00). This filter returns 120.00, so queries silently return a positive amount. The previous parser returned an invalid decimal for this input. Recognize the parentheses before filtering and test scalar and array values. (raw.githubusercontent.com)

Avoid silently removing decimal commas.

With glibc de_DE, PostgreSQL formats 1.23 as 1,23 €. This filter returns 123, whereas the previous parser returned an invalid decimal. Obtain the monetary locale or normalize values server-side; if that is not possible, reject values whose format cannot be interpreted safely. (raw.githubusercontent.com)
