首先尝试使用官方插件进行扩展，各种报错后放弃，不如自己修改源码吧。
一、官方解决方案
1、nocos 文档地址：Nacos 配置中心简介, Nacos 是什么 | Nacos 官网
2、官方解答：nacos支持postgresql数据库吗 | Nacos 官网
3、源码下载地址：Release 2.3.0 (Nov 30, 2023) · alibaba/nacos · GitHub4、Nacos的数据库插件仓库：nacos-plugin/nacos-datasource-plugin-ext at develop · nacos-group/nacos-plugin · GitHub
按照官方的方案，下载插件后，更改pom文件中nacos的版本，之后将插件打成jar包，放到nacos的plugins目录下，更改配置，启动后各种报错找不到方法，遂放弃。
二、更改源码
1、在项目根(nacos-all)下的pom.xml文件中添加如下依赖：
<postgresql.version>42.3.8</postgresql.version>
org.postgresql postgresql ${postgresql.version}
2、在项目的nacos-config-plugin、nacos-persistence模块的pom.xml文件中添加如下依赖:
org.postgresql postgresql
3、在项目的nacos-plugin模块的nacos-datasource-plugin模块com.alibaba.nacos.plugin.datasource.impl包下新建一个包,名为postgresql,拷贝同级包mysql下的所有文件到postgresql包下，修改类名和文件名为xxxByPostgresql，如图
4、将这几个类中LIMIT ?,?的写法为OFFSET ? LIMIT ? 如图
5、在改项目resource目录下，找到com.alibaba.nacos.plugin.datasource.mapper.Mapper文件，在后面追加：
com.alibaba.nacos.plugin.datasource.impl.postgresql.ConfigInfoAggrMapperByPostgresql
com.alibaba.nacos.plugin.datasource.impl.postgresql.ConfigInfoBetaMapperByPostgresql
com.alibaba.nacos.plugin.datasource.impl.postgresql.ConfigInfoMapperByPostgresql
com.alibaba.nacos.plugin.datasource.impl.postgresql.ConfigInfoTagMapperByPostgresql
com.alibaba.nacos.plugin.datasource.impl.postgresql.ConfigTagsRelationMapperByPostgresql
com.alibaba.nacos.plugin.datasource.impl.postgresql.HistoryConfigInfoMapperByPostgresql
com.alibaba.nacos.plugin.datasource.impl.postgresql.TenantInfoMapperByPostgresql
com.alibaba.nacos.plugin.datasource.impl.postgresql.TenantCapacityMapperByPostgresql
com.alibaba.nacos.plugin.datasource.impl.postgresql.GroupCapacityMapperByPostgresql
如图：
6、在DataSourceConstant类中增加pgsql的常量
public static final String POSTGRESQL = "postgresql";7、persistence模块，修改PersistenceConstant
public static final String POSTGRESQL = "postgresql";修改ExternalDataSourceProperties类
代码如下，直接复制粘贴即可：

public static final String OFFSET_LIMIT = "OFFSET ? LIMIT ?";persistence.handler.support中新增PostgreSqlPageHandlerAdapter类，如图：
代码如下：
package com.alibaba.nacos.plugin.auth.impl.persistence.handler.support; import com.alibaba.nacos.config.server.service.dump.DumpService; import com.alibaba.nacos.persistence.constants.PersistenceConstant; import com.alibaba.nacos.plugin.auth.impl.constant.AuthPageConstant; import com.alibaba.nacos.plugin.auth.impl.model.OffsetFetchResult; import com.alibaba.nacos.plugin.auth.impl.persistence.handler.PageHandlerAdapter; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import java.util.ArrayList; import java.util.Arrays; import java.util.List; /** * @author w */ public class PostgreSqlPageHandlerAdapter implements PageHandlerAdapter { @Override public boolean supports(String dataSourceType) { return PersistenceConstant.POSTGRESQL.equals(dataSourceType); } @Override public OffsetFetchResult addOffsetAndFetchNext(String fetchSql, Object[] arg, int pageNo, int pageSize) { if (!fetchSql.contains(AuthPageConstant.LIMIT)) { fetchSql += " " + AuthPageConstant.OFFSET_LIMIT; List<Object> newArgsList = new ArrayList<>(Arrays.asList(arg)); newArgsList.add((pageNo - 1) * pageSize); newArgsList.add(pageSize); Object[] newArgs = newArgsList.toArray(new Object[newArgsList.size()]); return new OffsetFetchResult(fetchSql, newArgs); } return new OffsetFetchResult(fetchSql, arg); } }在 PageHandlerAdapterFactory 类中加入以下代码：
9、最终，执行打包命令
mvn -Prelease-nacos clean install -Dmaven.test.skip=true -Dcheckstyle.skip=true -Dpmd.skip=true -Drat.skip=true -U
根据需求，在nacos-2.3.0distribution arget 目录下找到打好的包
修改配置文件，记得将数据库ip、库名、schema名称、用户名、密码配置改成自己的：
spring.datasource.platform=postgresql db.num=1 db.url.0=jdbc:postgresql://xxxx:5432/nacos?currentSchema=public&reWriteBatchedInserts=true&useUnicode=true&characterEncoding=utf8&serverTimezone=Asia/Shanghai db.user.0=xxxx db.password.0=xxxx db.pool.config.driverClassName=org.postgresql.Driver nacos.core.auth.plugin.nacos.token.secret.key=SecretKey012345678901234567890123456789012345678901234567890123456789 nacos.core.auth.enabled=true nacos.core.auth.caching.enabled=false nacos.core.auth.server.identity.key=nacos nacos.core.auth.server.identity.value=nacos最终，祝大家成功！！！
