[BUG]: data loss when using timestamp(3) and push command

[egoist]

What version of drizzle-orm are you using?

0.30.8

What version of drizzle-kit are you using?

0.20.14

Describe the Bug

When I have the following in my table schema:

createdAt: timestamp("createdAt", { precision: 3 })
      .notNull()

when I run drizzle-kit push:pg drizzle-kit somehow thinks timestamp(3) and timestamp (3) are different and causing the table to be truncated:

Expected behavior

there shouldn't be data loss

Environment & setup

No response

I encountered this same issue too, my only 'hack' was to set mode to string:

  createdAt: timestamp("created_at", {precision: 3, mode: 'string' })
      .notNull(),

which outputs a timestamp(3) sql query with no whitespace.
this isn't good because it requires manual management of timestamps and changes to application code.

EDIT: you can temporarily fix this by deleting the space in the template string on this line:

drizzle-orm/drizzle-orm/src/pg-core/columns/timestamp.ts

Line 57 in 4706ad1

const precision = this.precision === undefined ? '' : ` (${this.precision})`;

If you compare the function to PgTimestampString you can see there is no whitespace:

drizzle-orm/drizzle-orm/src/pg-core/columns/timestamp.ts

Line 121 in 4706ad1

const precision = this.precision === undefined ? '' : `(${this.precision})`;

For a release, I guess this will need a deeper fix with the push logic to handle / ignore these discrepancies.

Having the same issue, this occurs with every single db:push command (even when there was no change to timestamp).

Removing the precision fixes it.

Opened a PR w/ @JohnGemstone 's fix:
#2278

I've also pushed a fixed npm package that can be used temporarily (https://www.npmjs.com/package/@kengoldfarb/drizzle-orm):
"drizzle-orm": "npm:@kengoldfarb/drizzle-orm@^0.30.11",

Should be fixed in latest versions of drizzle-kit! Feel free to reopen if it's not fixed for you!
