Question

我正在使用PostgresSQL 9.6，并且具有对数据库进行自省的过程。我有以下错误：

org.postgresql.util.PSQLException: ERROR: column "attidentity" does not exist
  Position: 169
    at org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse(QueryExecutorImpl.java:2440)
    at org.postgresql.core.v3.QueryExecutorImpl.processResults(QueryExecutorImpl.java:2183)
    at org.postgresql.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.java:308)
    at org.postgresql.jdbc.PgStatement.executeInternal(PgStatement.java:441)
    at org.postgresql.jdbc.PgStatement.execute(PgStatement.java:365)
    at org.postgresql.jdbc.PgPreparedStatement.executeWithFlags(PgPreparedStatement.java:143)
    at org.postgresql.jdbc.PgPreparedStatement.executeQuery(PgPreparedStatement.java:106)
    at org.apache.commons.dbcp2.DelegatingPreparedStatement.executeQuery(DelegatingPreparedStatement.java:83)
    at org.apache.commons.dbcp2.DelegatingPreparedStatement.executeQuery(DelegatingPreparedStatement.java:83)

我必须修改表吗？有指导吗？

Answer 1

逻辑复制和副本身份已在PostgreSQL v10中引入，因此您不会在9.6的pg_attribute目录中找到该列。

PSQLException：错误：列“身份”不存在
