Convert Postgres IPv6 column TEXT field into JSON

Trying to convert a text field to a JSON field in Postgres. The field was an IPv6 address those having multiple semicolons e.g.: “14:eth1:vTA1:::4:”

Trying to run smth like:

ALTER TABLE data ALTER COLUMN ipv6 TYPE jsonb USING ipv6::jsonb;

Results in:

Failed to convert text field to JSON. Details: invalid input syntax for type json DETAIL: Expected end of input, but found “:”.

Any clues how to do it properly?

Answer

Use to_jsonb rather than ::jsonb.

ALTER TABLE data ALTER COLUMN ipv6 TYPE jsonb USING to_jsonb(ipv6);
