问题
I'm using Postgresql and spring boot 2.0.4. The below error is thrown when trying to execute the queries one after the other. I've executed the following query, and the count keeps on increasing.
SELECT COUNT(*) FROM pg_stat_activity WHERE state ILIKE '%idle%';
I've used these properties and dependencies for connection pool. Yet, it gives the same error
spring.datasource.dbcp2.initial-size=10
spring.datasource.dbcp2.max-total=25
spring.datasource.dbcp2.pool-prepared-statements=true
spring.datasource.hikari.max-lifetime=600000
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-dbcp2</artifactId>
<version>2.1.1</version>
</dependency>

In Spring Boot 2.x, Hikari is default connection pool so if you have JPA then you don't need to add Hikari dependency in pom but if you want to use dbcp2 then you need to exclude Hikari and add dbcp2 dependency.
So in your case you mixed settings for both.
if just would like to stay with Hikari then remove dbcp2 dependencies and change your data source properties to use spring.datasource.hikari.
Add below properties to validate connection:
spring.datasource.testWhileIdle=true
spring.datasource.test-on-borrow=true
To further check if there is any leak, please add below properties and check how goes your pool connection and if there is any leak.
spring.datasource.hikari.leakDetectionThreshold=2000
logging.level.com.zaxxer.hikari=DEBUG
