ENUM error : synchroize doesn't check if enumtype already exists in postgres

[jeromeSH26]

[ ] bug report
[ ] postgres

when synchronise is on, typeorm doesn't check if a enum type already exists when using "enumName" .

I guess a IF NO EXISTS is missing somewhere

	@Column({
		type: "enum",
		nullable: false,
		enum: ECountry,
		enumName: "ecountry",
		default: ECountry.TODEFINED,
	})
	countryBudget: ECountry;

error is the following (type already exists)

query failed: CREATE TYPE "ecountry" AS ENUM('FR', 'GR', 'TODEFINED')
error: error: le type « ecountry » existe déjà

I still got this error in 0.2.29, and your linked dupliate issue is "Update dependency mkdirp to 1.x"

Why is this closed?

GitHub autocomplete seems to have a strange behavior where it selects a completely different issue number than the one you typed, and I presume that's what has happened here. Correct one is below.

Also running into this issue after squashing migrations. Does anyone have solutions for a workaround?

I have been manually editing the migrations files after generation

@Distortedlogic for things like CREATE TYPE ... what does your query look like? Any examples would be helpful! Are you just updating the queryRunner.query(...) command or doing something else??

[Distortedlogic]

@sepiette If u use the same Enum in multiple tables, when the migration is generated, it will attempt to create the Enum multiple times, once per table it is used in. Simply remove the extra lines of queryRunner that create the Enum. Yes, the lines that create the Enums will look like Create Type ...

As u can see in the screenshot, there is only one create line per Enum because I removed the duplicates after generating my migration which resolves the issue (or at least it does in my case). hope this helps
