Build failure on a project running on TS 4.7.4

[ilyakivilev]

This project have seen successful builds until recently. Looks like pg-protocol switched to TS ^6 starting v1.15 which is a breaking change for those running on older versions.

Build log is below.

node_modules/pg-protocol/dist/serializer.d.ts:34:18 - error TS2315: Type 'Buffer' is not generic.
34     flush: () => Buffer<ArrayBufferLike>;
                    ~~~~~~~~~~~~~~~~~~~~~~~
node_modules/pg-protocol/dist/serializer.d.ts:35:17 - error TS2315: Type 'Buffer' is not generic.
35     sync: () => Buffer<ArrayBufferLike>;
                   ~~~~~~~~~~~~~~~~~~~~~~~
node_modules/pg-protocol/dist/serializer.d.ts:36:16 - error TS2315: Type 'Buffer' is not generic.
36     end: () => Buffer<ArrayBufferLike>;
                  ~~~~~~~~~~~~~~~~~~~~~~~
node_modules/pg-protocol/dist/serializer.d.ts:38:21 - error TS2315: Type 'Buffer' is not generic.
38     copyDone: () => Buffer<ArrayBufferLike>;
                       ~~~~~~~~~~~~~~~~~~~~~~~

Options to resolve I found:

1. Pin pg-protocol to v1.14 via overrides which is not ideal
2. Switch my project to TS ^6 potentially bringing other compatibility issues

Is this possible to keep pg-protocol on the older TS version?

Are you using pg-protocol directly? If this happens when using pg-protocol only via pg, I wonder if there’s a way for pg to hide that implementation detail.

@charmander I am using pg. The error just reveals it's actually coming from an underlying pg-protocol dependency.
