- Around line 305-308: The jOOQ generation target packageName element currently

which is incorrect for this Liquibase-based project; update the <packageName>

that pairs with directory target/generated-sources/jooq) to a clear, accurate
package such as "com.example.poc.webmvc.jooq.db" or
"com.example.poc.webmvc.generated.db" so generated sources reflect the project

org.springframework.batch.infrastructure.item.database.AbstractPagingItemReader

getPage(), and getPageSize().

Spring Batch types: remove the wildcard and add import
org.springframework.batch.core.BatchStatus (since BatchStatus is the only symbol
used from that package here), keeping the existing explicit imports for Job,
JobExecution, JobExecutionListener, Step, JobBuilder, RunIdIncrementer,
JobRepository so there are no conflicting/duplicate type resolutions.

- Around line 12-13: The static field declaration uses the raw
PostgreSQLContainer type which causes unchecked warnings and loses fluent
generic typing; update the declaration for sqlContainer to use the wildcard
generic PostgreSQLContainer<?> and construct it with the generic-aware
constructor (e.g., new PostgreSQLContainer<>("postgres:18-alpine")) so the field
reads as PostgreSQLContainer<?> sqlContainer = new PostgreSQLContainer<>(...) to
restore type safety and avoid warnings.

Constructor must call setPageSize(1) and should override setName() with the concrete class name.
Critical — missing setPageSize(1):
doReadPage() adds exactly one element to results per invocation. AbstractPagingItemReader.doRead() only calls doReadPage() again when current >= pageSize. With the default pageSize = 10 and results.size() == 1 after the first doReadPage() call: after yielding index 0, current becomes 1, which is less than pageSize (10), so no new page is loaded. The next doRead() call computes next = 1, 1 < results.size() (1) is false, and returns null — the end-of-data signal. The reader will process only the first page and terminate.
Moderate — setName() uses the abstract class name:
AbstractPagingItemReader's default constructor calls setName(ClassUtils.getShortName(AbstractPagingItemReader.class)), which means all subclasses that don't override this will share the key prefix "AbstractPagingItemReader" in ExecutionContext. JpaPagingItemReader (and similarly JdbcPagingItemReader) each override this in their constructors with setName(ClassUtils.getShortName(<ConcreteClass>.class)) — CustomItemReader should follow the same pattern.

public CustomItemReader(PostRepository postRepository) {

+ setName(ClassUtils.getShortName(CustomItemReader.class));
this.postRepository = postRepository;

Confirm CustomItemReader needs listener interface implementation for .listener(reader) to work.
The chunk migration to Spring Batch 6 is correct: .chunk(2) followed by .transactionManager(transactionManager) is the prescribed pattern. However, the concern about .listener(reader) is valid—CustomItemReader does not implement any step-level listener interface (StepExecutionListener, ChunkListener, ItemReadListener) nor carries listener annotations (@BeforeStep, @AfterStep). The call will compile but the listener registration will be silently skipped.
The transactionManager placement after .listener(reader) (lines 39–40) is functionally equivalent to the documented style but does not match the Spring Batch 6 migration guide idiom of placing it immediately after .chunk(). Reordering would improve consistency with the documented pattern.
