FIX: pgsql: cast string_agg arguments
When converting MySQL/MariaDB
GROUP_CONCAT
calls to PostgreSQLSTRING_AGG
, an error occurs because of incorrect argument types (the literal','
that is added if noSEPARATOR
is given in the original call is of typeunknown
, for example).STRING_AGG
takes either(TEXT, TEXT)
or(BYTEA, BYTEA)
arguments (see https://www.postgresql.org/docs/12/functions-aggregate.html), therefore, I propose casting toTEXT
.
